Cellc

I called the Cellc call centre on the 1st February at 09:20-09:29. To let them know that I have a problem, the monthly installment did not go through(there was no debt) . The girl rudely told me that the money is reflecting on their side and that there is a problem with my bank. She was irritated that I needed assistance, I ended up not getting any assistance. Now 6 Feb, cellc is sending me messages to pay, worst now they will add charges for this. Can this be investigated cause am not happy.
