DOUBLE DEBIT, HARRASMENT AND POOR CUSTOMER SERVICE!!!

Where to start with the poor customer service provided by cellc !! What a disgrace and joke. As a customer of cellc you would expect to get some help when needed but with cellc's standards of customer service there's not much to expect. So I have an ongoing issue where for the month of August CellC debited me twice and when I called in they stated it was not their fault but my banks and said I should reverse one of the payments, so I did so and had to pay my bank R45. After a few days Cellc then starts harassing me for payment and telling me I'm late and when contacted Cellc they now cannot locate my payment after multiple cases logged and being advised that the timescale is 24 to 48 working hours for a response, no one contacts you about your case. When you call them for an update all they say is "Your case has been allocated to our back office team". At this point due to lack of customer services and any urgency I logged a complaint with them around the 25th of August and to date (09th of September) NO RESPONSE. For the month of September I was debited double plus a late charge even though I was not late after being assured that I will not be double charged by the representatives over the phone and in store. Not only have they charged me double but also tarnished my credit score with a missed payment marking on my name. Cellc customer services failed to acknowledge my dissatisfaction and just brushed it off with a don't care attitude and I'm disgusted by this. Dealing with cellc is like speaking to a wall because with this whole situation I have got nowhere but just a bad credit rating and money short in my pocket. SOMETHING NEEDS TO BE DONE ABOUT THE POOR SERVICE PROVIDED!!! I am at the point that I no longer want to deal with cellc will be taking my matter further with ICASA and definitely WILL NEVER BE A CUSTOMER OF CELLC EVER.
