STILL WAITING FOR REFUND/REVERSAL

I made an online purchase on the 26 April and went through he whole payment process as well as my FNB approval with OTP. Money was taken out my account by on the online portal an order number was not generated and the order was still in my basket. I have been phoning Mr price every day to get them to reverse the money and I am still waiting. the same thing has happened on paying my account. I am now waiting for Mr Price to refund/reverse R2000 . Every time I phone I get put through to a different department who then says it not them and transfers me back. I am caught up in a R2000 game of ping pong. no one wants to take responsibility and I am now beyond the tipping point and trying to get my money back.
