Vodacom users cannot contact me after porting to Cell C

I ported to Cell C a week ago from MTN (worst mistake of my life). I can make calls and receive calls from everyone except for Vodacom customers. Whenever a Vodacom user tries to call me it goes to voicemail saying my number does not exist. I have spoken to more than 60 people from Cell C who are all *********** and don’t know how to resolve the damn issue at hand. I believe it is a routing issue when I ported over to Cell C but non of the consultants understand what’s happening. They thereafter logged a case for me to which a lady called me yesterday (15/09/2025) and asked me to contact Vodacom instead. Vodacom cannot help me as I am not their customer. It’s been a week and I cannot receive any calls from Vodacom users including work, business or friends. This is really appalling. Can someone from Cell C please contact me urgently to resolve the routing issues I have when I ported to Cell C. Please can this person understand issues relating to routing.
