suspended line

once again without fail my line has been suspended for the third time for the month of December without communicating .1st they called on a Sunday to apologise this after I threatened to get my lawyers involved they activated it immediately ,they then then called to say I owe money for the month of august and requested proof because I disputed this , I sent through the proof but yet it was still suspended I asked why was my account not then suspended in august if they did not receive the money .. I didn't get an answer but yet my line is suspended I don't know how to express my frustration any more .the people in the call centre and store really does not know what they are doing ..I have all my slips showing proof of payment but because they don't know how or do not want to solve the problem which is clearly and most definitely on there end they look for stupid reasons to suspend my line .please I cannot complain about the same thing every month. I want my line to be activated again and have a manager to call, a manager that knows what's going on ..I can hear what they will ask of me ...please mrs lanagenhoven can you send the proof through again I
