Poor service E143 error codes over charged on debit order for Premium Package ON PRICE LOCK

I have installed 2 HD decoders since February 2019 on the Compact plus package paid cash without any hassles up until I app**** for Price Lock that includes the Installation, and the Explora and requested the Premium Package. When the Explora was installed everything went downhill. Installation was done end April and all 3 decoders was working perfectly yet still no Premium. ON COMPACT I called in several times requesting for a upgrade, did I mention when I app**** for Price Lock it was on PREMIUM. Well finally on the 6 May I was upgraded to Premium and everyone was happy except my MOM whom the one decoder did not work at all a on screen error showed E143 and after several phone calls money I can not claim for the issue could not be resolved it was escalated so may times......my story is actually a up and down and inbetween calls trips to multichoice and its sadly the worst experience or service I have ever received. Took all 3 decoders in to ne checked at multichoice well it work the one decoder with the error of E143 WERKED finally my mom can be in bed and watch her programmes. What a disappointment when I got home to check E143 again phone calls to multichoice etc. And yet still the decoder shows the error as soon as you plug in another decoder it works in her room. After the phone calls I gave up month end came and the amount to pay as per my knowledge is R1054.00 per month well R1443.00 was deducted from my account apparently its pro rata payment really now because I upgraded. In the 1st place I WANTED PREMIUM and not Compact. so why the Pro Rata clarity on phone calls needs to be checked when I app**** It was the Premium package from day one why would I have Compact plus and take a package on Compact please come on where the customer service you guys want business yet still no Customer Service at all. Last but not least I hope this matter will be resolved before my debit order goes off end off this month cause actually I am paying for Compact and Premium HAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHAHAHAHAHAH.................................................. and please do not tell me there is something wrong with lines or the installation was done incorrectly, I CAN PLUG IN ANOTHER DECODER AND WATCH DSTV AND IT WORKS I am tired of the E143 ERROR, TIRED OF THE escalations the calls the trips the alles I just want my house hold to watch tv and have no errors and no issues and no over payments as well.
