Vodacom account shows arrears but account is NOT in arrears

I am having a problem where Vodacom showing my account is in arrears but there is no money outstanding. When you phone the collections department it tells you straight you have phoned too much for the day and you cannot get to the collections department you must leave your number - saying that on the first call trying to get to the collections department - your robot gone whacky!!!!

When you phone the customer service and ask please tell me what is outstanding they say - hmmmm - you are not in arrears - I said according to vodacom I must be because they keep on saying I am in arrears - and when I phone it tells me YOUR ACCOUNT IS IN ARREARS - so how do I get this arrears issue resolved.

I have sent several emails to *** showing my proof of payment and stating my account is not in arrears - but I guess the past 3 days since the first mail is expecting wayyyyyyyyy too much from vodacom for assistance....

I have asked what I need to pay and the operator said no money is outstanding!
