Unable to receive calls

I have been unable to receive calls on my phone all day intermittently. Called Telkom twice with no assistance given from the call center. The second time I was put on hold for 30 minutes. Do you guys not know the CPA and hold times? I called in from a different number whilst still being on hold spoke to a team leader however she was not able to log a case due to the system being down. So when will I be able to receive calls again? I will be cancelling my 4 contracts with Telkom. Its ironic how when it comes to making calls I have no issue.... maybe because its your revenue involved. If some miracle happens that you try contacting me do so on ***
