Can't receive calls on Telkom Mobile BUSINESS line!

Telkom Mobile Business - for 10 days I have not been able to receive calls from certain numbers, I have been advised that the matter has been escalated but nothing has actually been done.

I have called in numerous times, been given a reference number and told to wait 2-24 hours but to no avail.

I have even gone in to their store and done a SIM swop in case that would fix the problem.

One callcentre agent advised that this is a known problem for SIM cards that we ported, surely they could notify their customers of known issues so we can plan accordingly? My number was ported more than 6 years ago!

Telkom don't take the matter seriously or offer to compensate for loss of trade, this is a business account and I require a working phoneline to operate my business.

Can someone please buy Telkom and shut it down, we don't need these parastatal legacy operators in our economy!
