Telkom Account Blocked due to Telkom Systems Failure

Last month I did an upgrade and added another contract, month-end the invoiced amount was debited but ever since 02 June my account has been blocked (on their system it show that I am not owing them) and since then till now I have spend close to R700 from data and airtime and have been disadvantaged by this and I have contacted your call centre 4 times and visited the local service offices (petrol and time) 3 times and still no help.

The number in question is ********** 720.
