Bad service, lack of product knowledge

I called on the 1st of March 2016, to check my outstanding balance for the contract phone that I had with cell c, I spoke to Delina she said I owe nothing(R0.00) & the account is permanently deactivated. I called from the no: ***<br> <br> I called again on the 2nd asked to be transferred to prelegal I was on hold for an hour then I dropped the call.<br> I called again on the 3rd at 10:24 AM from the same number and I was on hold for more than 45 minutes I spoke to the lady who was rude she said I must call select online , I called select online and they confirmed that they don't have my details on their data base, I called again from a landline this time still did not get a clear answer, So IM CONFUSED Am I owing CELL C Or Not, I am not happy with Cellc's service
