Stay far far away from Cornerstone, particularly from Ed in customer service. When my father died,…read moreI called Cornerstone to cancel his business phone lines. Cornerstone shut off the phones, but continued to bill his estate for months. Then they shut down our home phone line due to the account not being paid. I called to resolve the issue, and Ed told me, verbatim and in a snarky tone, "I can absolutely shut off your home phones!" He then insisted that we personally pay my deceased father's business line debts before we got our home phone line back. He was incredibly rude, had no interest in discussing options with a family in crisis, and to top it off, he put me on hold for an extended period of time to have a personal conversation with a girl in his office. I know this because I heard him begin the conversation before putting me on hold. I later found out we were being double billed for our internet, once from Time Warner and again from Cornerstone. I immediately switched my phones to Verizon. I suggest you stay far away from Cornerstone. I've never had less pleasant customer service experience, and I feel robbed by this corrupt company.

Multiple bad experiences with this company, and I've been warned by many people to avoid them…read more The most recent, and worst, was after we disconnected our business internet service from them. We made multiple appointments for them to pick up their equipment, and they never showed up for any of them. They keep sending us bills for the full MSR price of the equipment (which is 1/4 the cost on amazon), and are now threatening collections after they keep skipping appointments for equipment pickup. Customer service talks a great game, but it's almost as if they work for a different company, since the techs never show and billing continues to make mistakes. Customer service will apologize again and again, appearing to go out of their way to help, only to have the same exact issues repeat. Avoid at all costs. Even Time Warner has better customer service than this company.

When we needed the services to be done, the service person continually called the wrong number for me, (which they have my phone number on record) because it's my husbands and he was traveling out of town, somehow someone had that number and obviously he was busy to take a call. I own the company, I own the building, I have my name on the bill, but they send the bill to my husband :/. I had to yet again, tell them who the boss here is, and who pays the bills. Atrocious.

The salesperson took our information and said the next available appointment was the following Monday. We asked if Saturday might be available. He said he'd check and get back to us, but never did. We called again at the end of the week to check the status of our appointment and found out there was none. Our third call was on a Monday morning to request an appointment on Tuesday. The technician showed up just before noon and let us know that the signal was too weak to be useful. Bottom line: a waste of time.
