8ta Service Provision Failure

I use 8ta 3G internet at home to run my business. I've had it for five years. Since the 6th of March I have no coverage any more, thus I have no internet. This is a big problem to my business. I have phoned Telkom numerous times to report the problem. The call centre informed me that it has been passed on to David and they can do nothing more. I am not allowed to speak to David directly. He phoned me on the 11th of March and promised that someone will come out on the 14th to investigate the problem, but that did not happen. <br> <br> It's been almost 2 weeks that I am left without network coverage and I am frustrated because there is no urgency or desire to help from Telkom's side. The case number is 183 810 48.<br> <br> I have a similar problem where I requested unrestricted APN on the 11the of February 2016. I phoned more than 8 times between 11 and 22 Feb, was given a case number of 178 280 92 and told I should wait 48 hours each time. Until today (17 March) nobody has phoned me back regarding this case. <br> <br> My only option is to cancel my 8ta contract and move to a more reliable service provider.
