Mr Price not refunding what they should

I have complained before about the shocking service received from Mr Price with regard to my daughter. two years later and still nothing has been resolved.

You deducted cellphone and insurance payment from her for over a year - which she had cancelled - and owed her an amount of about R3000 - in June you refunded her R1400 which meant her account should have been in R1400 credit. as you would not refund her the cash to her account she bought some stuff with that credit and now you are saying she owes R850 or more which she doesnt. I have explained / she has explained - we had one gentlemen who said he was going to investigate and guess what nothing has happened - only that she gets harassed with calls about being handed over for non payment. I can guarantee i will never promote or open an account with Mr Price as their service is shocking. How can they treat a new person to the credit world so badly with out a proper explanation.
