Telkom is refusing to suspend my ****** phone(sim cards).

I have 3 accounts with Telkom. I lost my dual phone(2 telkom sim cards) and when I tried to go to the branch to do sim swaps i couldn't because i was told that one of the accounts is in areas. They gave me Telkom customer care numbers. When i phone customer service they told the same thing, they can only do sim swap once i cleared my outstanding balance. Currently im raising money to pay that debt. Now when i tried to get Telkom Customer Care Helpline to suspend or barred those numbers, again they told me they can't. NB: Someone is using my sim cards with my data, making phone calls and possibly also doing ******* activities.

I'm in serious distress regarding that.
