Bad service and no sense of urgency

I was recently billed twice for the same amount by Cell C . Two seperate transactions of the same amount I have called their customer care for the past two weeks to solve this and im still sitting with the same problem for two weeks !

I even sent througj my bank statement as proof.thay I was billed twice and notjimg has been done. And the attitude I got from numerous customer care agents wen I voice out my frustrations is appaling. There is definiltly no sense of urgency and the need to help a client .
