Pathetic C-Fibre service - bill overcharg and line not working

Utterly disappointed with the service received regarding my C-Fibre line. I have experienced the following which have not yet been resolved despite THREE calls to the contact centre (reference number given by cell-c CS039022): 1. Fibre line has been down since 22 Jan 2019 (a week and counting)! I was promised that a back-office technical person will call me but no calls despite the follow-ups. The issue could not be handled by the front office technical staff (3 of them) as there was breakage in the link (apparently). 2. I signed up for a 20mbps line for circa R900 p/m but charged twice for R1100 (which is for a 50mbps line). the contact centre confirmed that i am receiving 20mbps. i initally raised this query during Dec2018!

if i do not receive a proper response, i will cancel the debit order and will stop paying Cell-C.

i expect a refund for the 2 months overcharge, and i expect my line to be up and running immediately
