No Customer service

Its been 2 months since I logged a complaint regarding airtime being bought but not received. The amount went of my bank account but Cell C cannot give me an explaination or reimbur*****t for the amount taken but no airtime received. My previous case has been closed without resolving the problem. The 3rd or 4th case had been opened for this one case. Still no answers.. No feedback. Ive been divorced for 4 years and even send my divorce decree in order for them to change my surname, even that the cant manage to do on their system I need to go to a Cell C shop. I am really losing my patience and would not recommend Cell C at all.
