Cell C bad attitude and no response

On 27.02 .15 I have paid my cell c account for R 345.00 and I sent proof of payment to cell c. I have requested on numerous occasions that Cell c needs to refund my personal bank account and NOT my cell c account. Of course Cell c does the opposite and credit my cell c account from 28.02.15 to date I have not received the refund. No one bothers to call me back I call the centre almost 3 times a day only to hear that they will have to escalate it. I have spoken to a supervisor on 14.03.15 and her verified that finance department will release funds on 17.03.15 its now the 18.03.15 and still no refund. My debit orders have been rejected on my personal bank account and I have incurred bank charges leave alone the inconvenience of paying the rejected debit orders manually. I am sure if I am a day or two late in paying my cell c account my line gets terminated. I am highly frustrated and as a customer they do not give me the attention I deserve. Some of the consultants have bad attitude and do not wait for you to finish your conversation they interrupt and are rude. Consultants do not read the history of notes when they speak and provide incorrect information. I WANT MY REFUND NOW
