Cell C Fibre Horrible Service

I was a happy Greencom customer but had the misfortune of being handed to Cell C (think it was a buyout) a few months ago. To be fair the network has not been bad at all, it is the service desk that is unbelievably bad. The front line helpdesk seem to be unable to help with any fibre queries, they have to send an 'escalation to the back office'. The so called back office never responds to you or them, I have had calls 'escalated' for the last 5 days with no response at all. Every time you call the helpdesk you really get the sense that they would like to help but they are just as frustrated with no one from FTTH getting back to them. It is unbelievable that there are still businesses that can operate in this way, no one is held accountable for any escalations done. Horrible!
