DSTV

In April I phoned dstv customer service and I was told my account was up to date and my next payment is only due in May. I decided to make it easier and activated a debit order for my account, BUT THAT WAS THE BIGGEST MISTAKE!!! In May they deducted R3240.80 from my account and up till now after numerous attempts, the only answer I get every time is our accounts department will phone you. Why did you deduct so much from my account???? All I want is the surplus you deducted back, but now again I owe them R1000 due end of May. Utterly pathetic service
