Multichoice have lost the plot

I have paid my premium subscription annually in advance to Multichoice for probably the best part of 20 years DESPITE perpetual problems when switching between three homes with 5 decoders in total where they continually would suspend my service for no reason due to their technical issues when switching between 2 holiday residences and our main Johannesburg apartment . They did at one stage admit that there was a problem on their side with my profile. This would then entail either many lengthy cell calls at my expense to resolve the problem. Finally I had had enough and did not renew in May. It did not bother Multichoice that I left their diabolical service as there was no contact UNTIL I got a call from a collection agency this morning to say I owe them R200 odd. Well done Multichoice, please feel free to sue me.
