Unacceptable so sick of their terrible service

Seriously regret every having cell c as a service provider. Worst company ever. This is the second time I'm complaining about them and they really don't give a ****. They now owe me over R300 for all the bank charges for every time they think they clever and take R2500 and then R1700.00 from my account when I only owe them R899 a month my account goes into arrears because of them and them I get to told its an error then need to fix this now and pay me back. So over everything.
