Been waiting 2 months for Action on my Account to NO Avail!!!

App**** online for DSTV Premium Price Lock on 20 Sep 2017 to ensure I have this installed in my new place by month end. By 27 Sep I had not heard anything from Dstv regarding the installation as I received email & sms confirmation that my application has been successful. Called Call Centre only to be told it seems that my application still needs to be process and that will take a few days. Most disappointed I decided to go and purchase my own decoder and get it installed at my own cost. Called back the call Centre on Friday 29 Sep 2017 to CANCEL the Price Lock Decoder as there was no need for it anymore. Was assure it will be done and that it will be EXPEDITE... The following Monday, 2 October I get home only to find this Price Lock Decoder delivered to my new address while I was at work. Called Call Centre asking why this delivery was done seeing I cancelled it the previous Friday. Not much help, was again told, my case will be EXPEDITED and someone will call me back. By the end of the week no one had called me,I call back AGAIN and ask to speak to a Team Leader/Supervisor, stating my case. Was once again assure someone will call me and that my case will be expedite. By the following Monday I call back AGAIN as no one called me back once again, asked when this Price Lock decoder will be collected. Courier company contacted me same day and they collected it from me on 12 Oct 2017. So here I thought, they have their decoder back, the PriceLock contract should be cancelled and everything should be fine. NO...only to be rudely made aware on 20 Oct 2017 a debit of R2236 went off my bank account for BOTH decoders...they never cancelled the Pricelock Decoder...so once again back on the phone...being told the same thing over and over again ( some one will call you and your case have been expedited) and literally NOTHING happens. So this goes on back and forth cant even recall how many calls I made to Multichoice about this matter, only to have ANOTHER debit order or R1833 gone off today...so I am paying for a service no even in my possession anymore and getting NO feedback or assistance from this huge company at all. Please explain to me WHY it has to take 2 months to have a service cancelled and the paying customer has to call constantly for feedback and answers and being **** to every single time she calls and money taken from her account for a service she cancelled!!! I am beyond frustrated and need serious action and answers!!! Sincerely hope this medium allows this matter to be resolved immediately!!!
