Horrific Service / Bad attitude

I made an online order for Builders Fourways. I was called to ask if they could deliver on the holiday and I was told they were busy loading the car and will be at my house in 30min. I live 5km from the store. This was at 11h15. 13h20 still no delivery and I was supposed to leave for a function at 12h30. Clearly some "special" people were prioritized over me and they decided I could wait since I'm not a special person. I call the call centre at 13h30 to enquire about why my order was not delivered and I'm told they claim they came and I didn't open. I checked the log and the first intercom dial of my house number for the day was at 13h35, so that's a lie!! I call to get a discount today, after having the phone put down on me by the Fourways store 5 times mid-conversation, I finally get someone at the online department willing to engage me. They tell me the order was "dispatched" so they can't reverse the money on my credit card, I have to send my bank statement and ID to head office before I could get MY money back! You're not going to force me to spend my money with you via a credit note! I have no intention of spending another penny with you! GIVE ME MY MONEY BACK, It's MY money! I don't have to prove it, you have the details on your system to reverse the money back onto my credit card.

I got approached at the store by credit sales agents a couple of weeks back asking for my ID and Bank statement to open a credit facility even when I told the OVER AND OVER I'm not interested. I will not give my ID and bank statement to use for your other underhanded means, forget it! I want my money back!! Reverse the money back onto my credit card, it can't be that difficult!
