porting to telkom, what a nightmare

I have ported to Telkom last week Monday from Vodacom ( ********** 165) as the data deals looked very good. Since then I cannot receive calls. The message says the number you are dialing does not exist. I have called the call center, more than once to no avail I have logged online and chosen the chat to an agent. i was not assisted I have chosen the send an email option. Nobody has gotten back to me.

what more must I o for assistance.
