DSTV must Fall

Twice in less than two weeks DSTV have summarily cancelled my service citing non -payment. They repeatedly credit A.N Other account with my payments and cut off my service for A.N. Other not paying. Contacting them to submit proof of payment is a nightmare. The call center ladies are helpless, they gave me e-mail addresses that are known to be out of order, the team leaders are not available and as for contacting a manager one may as well try and catch the wind. It took me 6 hours, 9 e-mails and hours on the phone to 4 different call center ladies including a team leader (I had to hold for 15 minutes to speak to her ,but she was helpful)
