SD Tech has great reviews so I called them. Hank spoke to a tech and reassured me they could fix it. He scheduled the appointment for the very next morning. Dan arrived right on time and had my computer running in about 5 minutes. Hank and Dan were so friendly and responsive. I highly recommend SD Tech, whether it's for your personal computer or you are running a large business.

But these guys have it! Not only are they the best in the biz, but their prices are competitive and the value is undeniable. There's nothing like turning on all the computers, servers, and printers, and not having ANY issues. They'll be back when we need upgrades and updates, we love SD Tech.

Tony installed my outdoor TV antenna a few years ago and mounted a TV for me. At another…read moreappointment he hooked up another TV and promised to come back the following Monday with a bracket to hang it. That was about two years ago and although I keep calling and texting, he is ghosting me. Mounting the TV is not that big of a deal for me however, now I am getting lots of "no signal. Antenna not connected or program unavailable" on one of my TVs. Also, for some reason, not able to get the local CBS channel on one of the TVs anymore. Very disappointing he does not respond. Thought I was a good customer as I gave him one of my older working TVs that he said he could use. Time to move on.

This company does a great and professional job! Tony and Gabriel and very knowledgeable.read more

I am sorry to say this, but Grande has been changing for the worse in the last two years. Y'all can…read moreforget about my 5-star review back in 2020! Grande has been nothing but a pain for the last year, and I am just TIRED of their excuses. I work from home, and there hasn't been a single day where I lose internet signal more than 5 times a day (that is not normal). On some days, I lose signal for hours and I know what their answer is "unplug and plug back your router". It is so frustrating that doesn't matter what we do, we always have the same issue and the customer service tells me that if they send someone, and don't find a problem then I have to pay an additional fee for their "work". They used to be such a good company with amazing customer service, but I guess since their recent changes with Astound things have been changing for the worse. Definitely not coming back to Grande ever again.

Where do I start. Unfortunely the apt only allows Astound. But that isn't the problem. I sign up…read morefor internet service in the middle of Feb. Being a new customer with a $200.00 gift promotion. I thought my first bill will be in March to be paid in April. Come April I was already two month behind with of course a late fee. I call they wave the fee and paid my bill. The customer rep. ask about enrollment in auto pay and save an addition $10.00. So I did gave him my bank information. I though okay I don't have to worry about it. So Fast forward to June my service started to slow down and buffing became a nuisance. So I called again to find out that I again was behind. The rep. for some reason didn't complete my enrollment. Well I talk to another rep. explain everything that happen. This time I was told that they couldn't help me at all. I had two paid the two month and the late fee. I told her I have no problem paying it but can she please wave the late fee and charge me the amount I was told if I set it up for auto pay. I was told she couldn't. I ask about the promotion and she said I didn't qualify because supposedly it states that the customer couldn't fall behind. Well I guess I didn't read the fine print and I wasn't told this in person when I sign up for service. I just finish talking to another rep and he stated again there wasn't anything he could do. He also stated that if I didn't pay the complete bill including the late fee there was going to be another late fee because of the late fee I wasn't going to pay. WOW As for the promotion I guess I'm not receiving it. Okay keep your darn gift card but at least wave the late fee due to that it was your rep. that didn't follow through. I think I'm going to try internet service from the cell company.

A friend had just used CTI to service their phones and recommended them. I should mention we both have NEC phone systems. Anyway, their technician came out and was able to fix it for a smaller hourly rate. I think it was $90 or something. Totally reasonable price. And he was SO PROFESSIONAL and clearly knew what he was doing. The office people too - they're really easy to work with and always pleasant. We actually ended up buying a new system from them, and they credited us the cost of repairing our old one. Now I recommend them to everybody I can.
