Wrong Billing while on Pricelock & No responce from Management

I have been on Price lock package from last yer and I've been billed as advertised/agreement the amount of R539 until September 2017. I have spoken with several consultants including Supervisors and Managers (Lucky Legodi, Caiphus Molaudzi, Lethabo Tlali, Sinah Setlhabi and Lindiwe Hlongwane) and they all promised to fix this but its still not fixed.

Dissappointed as I am I still don't understand what make this matter unsolvable after 3 months of discussions with the following people Lucky, Caiphus and Lethabo, and some of them are supervisors in their divisions. The very last conversation with Caiphus ended as if we will never ever have this discussion again... here I am R654 was debited on my account in December 2017 instead of R539 which is continuing creating bad profile as some of my other debit orders bounce because of this inconvenience. I have just been told that R688.00 will be debited on my account again this month (January) instead of R539.00. Just to take you back where I'm coming from with this matter , it was September when I had to pay my account manually at Absa (paid it on the 5th and emailed proof of payment) . In October i paid manually again and emailed proof of payment on time. In November 2017 they debited R885.00 because the amount on my account was R550 to make sure that my debit order is honored it then bounced & I had to pay charges of R115.00 to the bank. I thought I'm closing this matter with DSTV consultant who promised me that the R539 price lock debit order will be returned to me with immediate effect after I pay a R770 , which i did and i even emailed the proof of payment. Immediately when i think of this i feel that i have done enough to show that I honor the contract I have with DSTV by responding immediately to any unpaid debits but on the other side DSTV were not fair to me. This time I choose not to write to Helopeter. I have send several emails & none of them were responded on.

This is really affecting my account profile. When I took this contract I was still working but I make sure even though that I am no longer working I have enough to pay my DSTV from my allowance I receive.

Thanks, Nosipho Dlamini
