i want my money Dischem

I went to DISCHEM Parkmedows on the 8 October to make a purchase. a double deduction was taken from my account of R1050. with many emails, phone calls, 4 visits to my bank as guided from DISCHEM up till today its still not sorted out. The Manager GRANT that I only spoke to on Monday after leaving numerous messages for, that didn't bother to make contact with me, also told me that he is actually doing me a favour by trying to sort out this matter. I was in your shop regardless if it is YOUR FAULT (DISCHEM) or the BANK, I think it is disgusting that I have to wait to long and that I (the client) have to spend so much time trying to sort out a matter that happened in your shop.??? I want my money in my account as soon as possible DISCHEM.!!! I've had enough of this and nobody is taking responsibility, and I would like some Owner or Manager to contact me and give me the answers and my money in my account.
