Account suspended without my knowledge, limit cannot be changed until the contract expires.

My account has been suspended without my knowledge, requested to change account to a top up , went to the store i was not assisted consultant gave me a turn around time of 24hrs also advised if i pay the minimum amount my account will be clear to do a sim swop i did a payment and now account still suspended, when i call the customer care i always get a recording saying they will send me self service message to log a query. The service is horrible i must say i want to cancel my account with Telkom its so pathetic.
