I ordered a free book How We Trade Options from a TV advertisement. After several months, I…read morediscovered I had been charged $29.95 a month for seven months (on my credit card) for a newsletter service that supposedly went with the free book. The only contact given was a website address. From researching reviews of the book on Amazon.com, I discovered the agency behind the promotions was National Marketing Resources out of Kearney, of which DataSource is connected. Even though I had never ordered the subscriptions and also I never received them, the company only agreed to credit three months of $29.95 and not the seven. My point is the free book offer is a bait and switch advertising ploy, Since I did not fall for that, it became a right-out scam in my case. The FTC says beware of offers that do not include a company's name and address. By the way, the book has many unfavorable reviews on Amazon, and many others see it in the same light as I do.

My fiance and I had been working with another company to this point on other orders but they were closed for the holiday weekend. Kat shared that if I got info to her on Friday, 7/2, I'd receive proofs that night. I didn't receive proofs until late afternoon of 7/6 and after our original company sent proofs after returning from the holiday. Kat & MEDiAHEAD's proofs were incorrect and late. I did not approve any proofs or agree to anything. Kat sends the email that's attached the night before our wedding. As this point, my only interactions with her is our conversation on 7/2. I went to their office to speak with a manager or someone not named Kat. Their staff seemed very aloof and not sure who else to talk to. I spoke with Mike and he joked that Kat can be a handful. He was not assuring or provided any support before telling Kat I was there. Mike was in no way helpful. I spoke with Kat and she was not authentic I her apology. She felt calling me a scumbag was warranted because I had ghosted her, held up her staff, and she had a bad day. She also shared that she apologized to the venue that referred us to her. If it wasnt for me coming to their office, the only apology that would have been issued was to the venue and not the actual person who was called a scumbag. She had put the effort in to reach out to the venue and she had the effort to craft an email to tell me I'm a scumbag but could find the effort to admit any fault. Very disappointing. Additionally, she accused me of having shared their artwork with our original printer. That is entirely untrue and not possible given I received proofs from MEDiAHEAD AFTER the other company. From being called a scumbag for not purchasing nameplates, being alleged to sharing proprietary artwork with a competitor, to having my interactions downplayed, my experiences with Kat and the team at MEDiAHEAD was awful and would not recommend.
