Multichoice - Unacceptable service

I processed a payment to Multichoice on the 12 September 2015 at Pep home and unfortunately the cashier typed a digit incorrectly on my account number. Once i realized this error, i contacted and emailed Multichoice and sent them 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>
