Olympic Promo Unlimited Internet ,Mobile & Free Phone Sent Phone Did Not Give Promo Cant Use Phone Was Billed $110 They Can't Find Contract

Most people heard about the promo during the Olympics $35 Unlimited internet ,mobile & a free Samsung A25 phone It ended on 8/12 , I signed up for the promo 8/8, ported a # they said the phone would be shipped when I receive the phone to  activate it & they would transfer my Xfinity # to the phone , I get the phone didn't activate it I was waiting to get my screen protector & case,  they did something to my current phone line because I'm not able to make calls,text or receive sometimes I dealt with this thinking that the other phone will be activated soon, then I check my bill I'm being  charged for two lines charged for the free phone and nothing changed with my home internet bill , total charges about $110. Instead of $35 ,then when I called I was on the phone for over 3 hours when they transferred me back and forth from mobile to Internet 16 times because they said it wasn't there dept then someone said it's messed up alot going on asked if I wanted to get the new promo and didn't know of any promo like I said I signed up for they couldn't find the contract like I was making up the promo I thought I was going crazy like being in the twilight zone,then waited to speak to the supervisor for 30 mins then got disconnected so if I never signed up for the $35 promo why did they send me the A25 If anyone has had this same issue let me know because there are things that they did and did not do for me I have the documents and my lawyer has looking them over also this is how they treat a diamond member of 16 + years 

Here is the link to the commercial for the promotion that I signed up for that the agent said never existed
