Poor customer service

<p>I had a cell phone contract with Cell c but the I settled the account in December.In January they deducted from my acc the exact amount I payed for my settlement.When I called customer service they said they can only return the money withun 5 working days.I went to the bank and reversed the debit order.Now I called in to request a payed up letter since it is still showing that Im paying them.I spoke with a consultant that said they will email it to me,i gave her my email adress.Its been 5 days and im still waiting for it.I called in again and I spoke with someone from legal who said they dont deal with settled accounts,she transfered me to another department and they also said they dont do payed up letters.She then transferred me back to legal and they transferred me to customer service and that consultant decided to drop the phone on me.I have never received such service.Now I dont know how or where I will get the payed up letter</p>
