Incorrect Billing and frustrated customer

I am so frustrated with DSTV. We took a price lock with DSTV and was up to date with payments WEF September 2019. I have requested statements via the call centre and they said their system was not working. I asked for reconciliations via facebook messenger and via agents but to no avail. Now I get disconnected and get told I owe 2900. I paid 1900 and apparently I have Showmax I didnot subscribe to showmax. This I had with the premium package. I get given ref but pricelock did not call ref***2 i694 by team leader natasha silnehlanhla and again on tuesday. I was connected but was told pricelock will call to resolve but to date no one. I was put on hold for over an hour and then get disconnected wanting to speak to a manager because zonke transferred me to anele on ref ***2 i704 after an hour I get disconnected again. I refuse to pay showmax as I did not request. I want proof . I need my services restored and billing resolved. I am sick of the services we get.
