Multichoice Complaint

For the past two years multichoice have been billing me for a price lock plan I never had and everytime I call they saying they put on a not on the plan that I shouldn't be billed and they will escalate it to the relevant department and its now been 2years, my services are suspended weekly, I call in weekly just for them to reconnect I fail to.understand why I can't be treated like any other paying coustomer and the worse part consultants give me attitude and end up saying there isn't anything they can do I have now been paying for more than 3months bit it says I owe R900 and I'm on a compact plan......this is really embarrassing and a bad experience with Multichoice if it takes that I cancel all my decoders and all contracts with multichoice then so be it im fed up.
