Dstv bad service/Channels blocked

I made a payment on the 25 Feb on a Saturday using EFT. My channels have been blocked three times,every time I am asked for proof of payment.i have even emailed the proof of payment but to date I am asked to provide a proof of payment and references. The call center agent I spoke too today has also been very rude and telling me it's my choice if I don't want to continue using their services. Though I have explained that my channels were working because it's over 10 days that I have made the payment.
