Sim card Suspended

My LTE contract sim card has been suspended by Telkom since Thursday. The sim card can only be suspended if I request it or if I missed a payment and in errors. I'm not in errors nor did I request it to be suspended. When I phone their call center I'm told it's a system error which they have sent to the back office to fix and unsuspend my card but that can take anything between 24 to 48 hours. I've paid for a service but I'm not receiving it.
