credit limit system error

<p>Well, i have a contract with vodacom and my sim card started acting up. i had to do a sim swop on 10/09/2016. the sim swop didnt take effect because documentation was not submitted. when i phoned vodacom 111 the lady got the sim swop submitted and working. Sunday the sim stopped working and the account limit was reached, this limit reached is a system error since i have not even used 15% of my contract, AGAIN i had to phone in to unlock the sim. Tuesday 13/09/2016 the consultant found that there is an irregularity and opened a case to a support specialist. im a customer and i want to use my contract, when there is a system error like this the support tickets on one number must raise a flag if the same number is phoning in 6 times in the last week.<br />my sim card still blocks on a limit every day after 8. im considering to cancel the contract due poor performance</p>
