Pathetic service

I've called Cell C for 3 weeks straight to ensure a smooth cancelation process of Fibre. Needless to say Cell C still messed it up. After numerous confirmations, they still deducted for the month after cancelation month. Then they have the nerve to tell me to wait 14 days for a refund. Lol. I had to call them in the following month to inform them that their own line is still on after cancelation date. They still haven't informed the Fibre installer to switch off the line and we're now 6 days into month after cancelation. What a joke.
