Complaint Review: Direct TV Refer a Friend

I got Direct TV in July 2017 and was given a refer a friend promo card from the installer w/ his code on it. To get the $100 I had to send in two copies of my paid bill statements along w/ the promo code and my friends info. I did everything it said and the waiting game began. After no recieving anything I called this past February to get an update. They said I wasn't in the system so the technician took all my info and entered it into the system and said I was all set and that the rewards card would go out April 10th 2018. Well it's the end of May and still no rewards card. I called them again last week again took all my info and updated everything. The techy said I was all set my account has been updated but she didn't have authority to issue the card so I'd have to call the number she gave me and have them refer to the notes. I did so today ended up calling 3 different numbers and spent over an hour of my time and still got nowhere. They said too much time has passed and I'm not eligible. I kept telling them all the delays were on their end not mine. I followed procedure and they are screwing me and others. I kept my end of the bargain and they are not. They even said I don't exist in the system but yet they find me every month to bill me. And they also said the have no record of any call I made to DTV in February.
