Bad service

It’s been 2 full weeks today since I wrote a review about cell c not being able to do a number change on my contract to my primary no. I still have to change SIM cards when making calls.l which is a problem and why must I do that when there’s an option. They have not contacted me telephonically to resolve the issue only responded here with “we ll get back to you as soon as possible. I’m just wondering what more I can do since this platform did not help me resolve this issue u and when I call the call centre there are no answers. This has been their response last week on the 7th “We have received your query and will attend to it shortly. Your reference no is: ***. An SMS will be sent to you when your query has been resolved.
