Bad service from multichoice

Mutlichoice keeps messing up my billing every month without fail i encounter a problem with amounts and debit dates

Last month i requested the date to be amended to the 15th of each month and was told to pay cash which i did now my services is suspended again and i keep on having to pay reconnection fees

I am a pensioner and don't have extra to pay each and every time

Today I called for them to deduct the money as its available in my account they said they can deduct only on weekdays but today is a Friday

I need my services reconnected asap i cannot keep standing in long ques to make payments

My contact number is ***
