Problem since December with account billing

Since December I didn't receive any statement from Vodacom. Vodacom was double debiting my account and since then, my account statement is very confusing and it is really unacceptable. Sunday I was trying to log into my account online. Vodacom's site was \offline\"!!! Yesterday Vodacom cut my line because of an arrear amount. I've phoned the customer care and requested my balance. The system informed me that my account is R91??. I then phoned to speak to a consultant. I've hold the line for 110 minutes!!! The consultant told me that my account is only R3000 odd that I have to pay to reconnect my line. So I did pay R3150 and still the Vodacom site says that I am R6000 odd in ARREARS!!! This is UNACCEPTABLE!!!! VODACOM'S ACCOUNTS ARE SO CONFUSING AND THIS IS UNACCEPTABLE SERVICE!!! Or actually...there is NO service!!! My line was cut off yesterday without \"warning\" me!!!! Vodacom MUST please explain this scenario to me. According to the consultant I've spoke to last night, there are many unhappy clients regarding statement of accounts!!! WHY WHY WHY?????"
