PATHETHIC SERVICE

I had an issue with Cell C for debiting my account on the wrong debit date because the 24 September was a holiday so i have been back and forth with a lady by the name of Gabisile Ntombela,i send her emails for feedback and she has no sense of urgency let alone customer service to reply and just ignore,i had to keep mailing.Today i get an sms that i must liable for the extra charges cos of CELL C fault for debiting my account on the wrong date when for the last donkey years my account was always debited correct.Today i called customer care and spoke Mienie and she told me the charges are for the returned debit and thats not my fault.Calling the customer care is of no use and no one can seem to address the issue and assist.
