CFibre - Unreliable & Unprofessional

I've been without internet for almost a week now and absolutely nothing has been done to assist me. Support takes forever to pick up and when they do they are completely unable to help. They made promises to call me back with solution the following day but that has never happened.

After a lot of investigation from my side I figured out that my PPPoE credentials have been invalidated, despite all my bills being up to date. I've raised this to support but they have been unable to assist. They've promises to phone me with a solution later that day but that's never happen.

On top of this, I've been double charged for 3 months - and once I brought this to their attention and they promised to refund me. Suprise suprise... That hasn't happened yet.

I feel completely helpless and I'm ready to cancel my contract with them, but with the level of competence of their staff I fear that even that will take months.

I have absolutely no idea how I'm going to get my internet back up and running and Cell C couldn't care less.
