Incorrect billing

I am super upset and frustrated by your current billing, my instalments have drastically increased from paying R778 for my two decoders, I am now told to pay close to R2000. Apparently two amounts were reversed from my account of which I know I did not initiate those reversals. This spin the wheel thing really messed up our billing. Worst of it all your staff just tell you you’re owing and must pay the amount without even giving you any solutions, *********** as I may say. My debit order date has also been changed from the 25th to the 31st without my knowledge. Either dstv resolves this or cancel my subscription as I will not be able to pay such an amount..
