Telkom Contracts blues

I just renewed my contract with Telkom. My spend limit has been set at R0.50 and cannot access airtime from their various portals. This has left me with a handset where I cannot make a call (unless to another Telkom line). I cannot even recharge airtime from my bank account. I also wanted to speak to a call centre agent about my other contracts but their customer care number leads to automated responders who cannot handle my issue. I think Telkom is ****ing their brand by making their clients talk to machines than human beings. After many service providers disappointed me, I thought I found home at Telkom.
