Once again Multichoice cant get my billing right

I upgraded my service on Sunday to the full premium service and was advised that I need to pay an additional R58.00 when I make my payment on the 27th to include the 5 days that I am using the premium service. Yesterday I received an SMS telling me that my full payment of R969 was due on the 24th January or I would be disconnected. I called the call centre today (23rd) and spoke to Portia Mpe - well not much success with her- she kept on telling me that the SMS I received was linked to my dead mothers account !!! So I asked her how come my premium for this month and the amount due by my dead mother (5 years already) were the same - she didnt know. She also told me in no uncertain terms that no messages had been sent to me - so now she is psychic and can see my sms on my phone as well. What a terrible attitude. She assured me that I could still pay on the 27th but I know without a doubt that tomorrow my service will be disconnnected and I will be liable for the reconnection fee - why - because Multichoice has done this to me before - not once but twice. The billing system is probably the worst in the world - for a " world class" provider wanna be they are 3 world with their billing - Lets see if any one bothers to call me or guaranteed I will be disconnected tomorrow - pity we dont have another satellite provider ..
