Horrible service from service consultants. No assistance received

Dstv linked my account to someone elses details and yet my account gets billed monthly. Dstv has a cellphone service which is linked to a phone number and the id number is also always linked to a cellphone number. Dstv has linked my number to another members details and refuses to unlink. I have called over several months to explain. now today on the 7th of Jul 2018. i have spoken to 3 customer service agents who have refused to assist. Lerato, Thabo and Sthembiso with the last agent saying that she will not unlink my number unless i contact the person. i requested that she gives me the persons contact details and she refused. i asked that she escalate and she said that it won't help. her response is that, because i know who the person is i must contact that person and tell the person to give me consent to unlink. she even says that she will not call the customer to verify if the details that they have mistakenly linked are his or not. DSTV customer consultants are really unpleasant. The only time things are smooth is when my account is debited. its even worse because i am on Premium but i cant even reap the benefits.
