DSTV customer service is pathetic

They the most pathetic service. I have been a customer for more than 10 years last month I was offered an upgrade for 2 months at a reduced subscription I have always paid by debit order and now my service is disconnected 2 days before the debit order date for an outstanding amount that is twice the amount due. 4 phone calls later that last up to an hour and every one promises to call you back and no one does. Customer service is the worst. I can do without this trouble in my life and I think I’m going to cancel for good.
