DSTV *****S OVER R9K AND WONT HELP ME!!!

Last week, i made a payment through my DSTV app. For some reason the system charged R10 240.48 instead of R983. 00 i called DSTV immediately and they failed to put me through to financing. The next two days i struggle for them to assist me. First they wanted a pdf form of the proof of payment. The option to charge through the app doenst ask you if you would like a proof of payment. Go check it multichoice and see. I called the bank, went in and even talked to them through the FNB app and the bankers all said that no proof of payment can be pulled only the authorization code of the transaction and that any merchant will be able to pull the sale. Called multichoice again and they lady left me on hold for quite some time. The told me that all i need to do is send ID, confirmation letter from the bank and the authorization code. I sent it and today get a reply they cant help me if i dont have a pdf of the transaction!!! Multichoice now sitting with over R9000 in the festive season and dont give a **** about me! No assistance just blatant ignorance!!! DO NOT USE THE MY DSTV APP!!!! IT WILL TAKE YOUR MONEY AND YOULL NEVER SEE IT AGAIN!!!!
