Unacceptable service

I processed payment to Multichoice on the 12 Sept 2015 at Pep and unfortunately the cashier typed a digit incorrectly on my account no. Once i realized this error, i contacted and emailed Multichoice and sent the proof of payment and requested for this error to be rectified. After 4 emails and 6 months later, i have still not heard from them or had any correction processed on my account. They have however informed me during this time that my account is overdue and i had to process a duplicated payment because the original payment made was allocated to a Suspense/Unallocated account. This has impacted me financially and the attitude of Multichoice would seem that they don't care about their customers or service to their customers. I find this unacceptable and would like this matter resolved urgently. For customers to wait 6 months for action is not acceptable.<br> I logged a report on the 16th March on Hello Peter and initially it seemed as if Multichoice was going to rectify the matter but after sending them the proofs of my overpayment, the last feedback received was the 17th March. I have followed up, but still no replies.<br> Multichoice needs to look at their ser
