DSTV continues with disgusting service

After four months of trying to resolve debit order overcharges, I had a call from Zanele today responding to my emails. She advised that my account had been credited with R169 and this would reflect on my account if I logged in. The account reflects a credit of R119 and an incorrect balance! Earlier I was advised that my debit order for 3 Jan would be discounted by R25, so I have no idea as to what will be deducted as DSTV clearly has a problem with simple arithmetic. This is absolutely unacceptable when I am a Price Lock subscriber with a fixed 2 year contract price until April 2020. So it seems DSTV can "unlock" contracts so as to stimulate cash flow... I will carry on with my Box Office boycott as it seems I am powerless against the mighty DSTV, at least until next April. I now have Netflix, so guess what I will do in April?
