AT&T Lies to sign up people

I signed up for service and was told that I qualify to a $200 rewards card. Now they claim I don't qualify, adding new requirements AFTER installation. The new magically appearing requirements are:

- you must have switch FROM a competitor TO AT&T. just signing up for service at 1 of 10 locations you own isn't enough.

- It must have happened within the last 2 months.

- You don't get 200$, you get the competitors termination fee UP TO $200.

This is a blatant scam. I called back 5 times pretending to be a new customer and they lied to me every time. I recorded all these conversations. I contacted customer service and it was clear they deal with this a lot and had clear techniques to shuffle the customer from department to department while ignoring the actual issue. 4 hours, and 16 transfers later on a single call, it became clear this was not an honest company. I will be canceling my service today and filing paperwork and evidence with the BBB. 

I will never use AT&T again. I didnt even want a 200$ gift card, i would have signed up without it... but as a lawyer, I do not appreciate being lied to. I will seek others for a (Edited per community guidelines) (Edited per community guidelines) if BBB complaints fail to resolve the situation... this is obviously intentional and pervasive.
