Discovery channel complaint: Discrimination of the Disabled and Elderly

I am elderly and on SSD. My monthly payment is added to My direct express Mastercard at the beginning of each month. ATT is racking Me over the coals each month at $150.00 a month for very basic cable. So when I heard about discovery plus I thought it was going to be a real solution to the ATT problem and I could finally tell them where to put it. But as I soon discovered , discovery They are denying access because they will not accept payment with My direct express Mastercard .Direct express recently stopped supporting Pay Pal as well so beings I have no other credit cards to use for payment. So basically because I Am poor and disabled I’m being denied access .What are You really that concerned that You wont get Your $7.00 a month? I have other friends being denied for the same reasons. We have come to the conclusion that this is discrimination because of Our being on SSD
