***** committed - managers refuse to investigate and take call

My mother has been trying to get a hold of a manager at Cell C for days now. She is promised a call back everytime! When she went to the beach - the lady called the head office for assistance and AGAIN manager did not want to take the call? YOu are giving my mother a bad credit rating after she called you and asked you to change her debit order date and you are debiting an amount of R45 for a data card that she does not have, nor ever had. This is ***** and if this is not resolved and all funds refunded to her - we will open a case and we will launch a social media campaign against you and your questionable practices. Please send a detailed record of all debit order deducted and where the request for the data card came from. YOur understanding of what customer service is is absolutely despicable and you should really just close your doors.
