Dstv price lock nightmare

After having the price lock with @Dstv or @Multichoice I have been regretting my decision! I now sit with a bill of R1000 whereas I was told that my subscription is R689.00 when I ask the reason for that I got told about access points and installation fees how am I still being charged for installation six months after the fact? Calling the centre is also a waste of time as no clear answer is ever possible sometimes I am left thinking even the consulta don’t know their job or can’t explain the bullish😞t billing. I am so gatvol I am thinking of cancelling this nonsense or approach the ombudsman!
