BAD SERVICE

Hi , I paid off my cellphone contract on the 23rd February 2016 an amount of R 1313.21, however on the 22nd of March an amount of R 206.02 which was my monthly payment was debited on my account. I app**** for a new phone and was told i was gonna get 1GB for the first 3 months for free however on the 20th April they debited 410.02 where else my monthly payment is R 259, when i called on the 21st April i was advised i will be refunded my money which is the R 206.02 and R 151 (case number ***), i had to call almost everyday and i was told different stories by different agents, on the 25th April i was called and advised that i will only be refunded the R151 to my bank account but still to date i haven't received any amount, i then called again on the 29th and was told my query has bee escalated again, then i called on the 2nd May and i was told the money R 151 has been refunded to my cell c account but no bank account, then a new query was logged (case number ***)again for the money to be refunded to my account and this morning i get a call from this rude lady who told me i owe Cell C so i wont get any refund on my bank account. This is so unprofessional and the is no customer service at all nothing has been resolve and the agents are so rude i tell you. Can this be resolved i need my money back on my account and at this moment i dont want anything to do with Cell C. Regards Princess Mabasa ***
