Unapproved contract and service delay

In the past 5 months I’ve been having serious issues with DSTV MultiChoice, every month I need to call in because of my account its either they over charge me or suspend my account for no reason, I will wait on the call for hours and once someone assists me its either they don’t have the product knowledge, ive had a contract with them for 2 years now which charged R449,00, the contract came to an end in October automatically they put me in another contract which is R500 and something without my consent and ive never agreed to it and now they saying I owe them R693.31 mind you this is for the contract that they automatically decided to open without my approval. Now EVERY TIME I HAVE TO PHONE PROBLEM GETS ESCALATED WHICH IS SUPPOSE TO BE 24 HRS BUT MINE IS 60 DAYS AND COUNTING. THE LADY THATS ON THE OTHER SIDE IS VERY RUDE AND THEY WILL JUST KEEP QUITE MIND YOU ITS MY AIRTIME… A CALL OUT TO ALL DSTV CUSTOMERS WE ARE TIRED OF THE POOR CUSTOMER SERVICE THAT’S BEEN PROVIDED AND FRADUALANT CONTRACTS THAT WE DID NOT AGREE TOO.
