ROUND 2 OF BAD SERVICE

I Logged a complaint on Friday regarding my data that was not loaded as per my contract I signed. The query that was logged was closes noting that the issue was resolved but it was in fact not. I called the call centre this morning and they advised that they do not have the deal number and therefore can't load the data. I called the MTN store at Mall@Reds and was advised that the manager is dealing with it and it currently not in but would phone me back. It's now after 15:00 in the afternoon and still not response. I send a message with the details of the phone on the old complaint but still no response was received. THIS IS UNACCEPTABLE. I think I have been reasonably calm about this but I upgraded in March and it is now 15/04/2019. A month and a half has passed and nobody did anything.
