Poor service

I am currently a customer of cell c. Sandra McNamee *** I have a fibre line and for the last 2 or 3 days we have been having issues. I phoned cell c fibre support line 3times yesterday. The once the agent said they would phone me back. They didnt phone me back. The other 2 times I phoned was because I needed a reference number. I received an email with no reference number. I then sent 2 emails to customer service with a reference number. This morning I phoned cell c 3 times 2 of the times my call was cut. The 3rd time the lady said my reference numbers dont exist and the one reference is to cancel my contract? I did no such thing. I have been a customer of cell c for almost 2 years and this service is unacceptable. I need my fibre line restored as soon as possible. At this point I am not even sure if anyone has dealt with my call. If they know what's going on or even of the reference numbers are valid.

Please investigate
