Cell C Fibre Department - no response to numerous requests to book my fibre move on the 1st of April.

I have been trying to get hold of Cell C Fibre regarding the moving of our fibre for 2 weeks now. I have called on numerous occasionsonly to be passed around as no one seems to be able to give me any details, they always ask me to send an email, and it is always a different email address each time I call. I have now emailed more than 5 times and no one ever responds or calls me back to assist. My request has already been escalated (Ref ********** 645 on 26/2/2019), and I have also emailed your escalations department, but still I have had no response. We will be moving to our new house on the 1st of April. The new house already has Vumatel installed. I need this move to take place on the 1st of April, because I cannot have a gap without fibre. I work from home so it is very important that this move occurs simultaneously. Can someone from Cell C Fibre please call me urgently regarding this!! I want written confirmation that the move over has been booked for the 1st of April.
