still no billing details. overcharged

I switched off my subscription to DSTV Premium and PVR services. ie I was a month in credit via the self help in April/May 2015.<br> <br> DSTV changed their billing systems at middle of this year (around June 2015). I then moved to Cape Town and switched attempted to switch on my services in September 2015.<br> <br> I am requesting this billing information from DSTV in order to get clarity on amount of credit. I would like a full statement for the past 12 Months.<br> <br> In past calls to DSTV, the last operator, Ayanda had said that they have no records for any DSTV subscribers pre their new system installation. On my HelloPeter request , a Rupert Paulsen claimed dstv to have credited my account with R311 via an email. He has not provided any proof or billing. There is still no billing details attached.<br> <br> When I rep**** to his email, a new request was created on the DSTV automated inquiries email system.<br> Still no response from them there for over a week.<br> <br> Maybe DSTVs HelloPeter support channel can assist? <br> <br> Has DSTV got something to hide regarding their billing and their new billing system implementation?<br> <br> I am expecting a credit of around R780.
