Total shambolic online ordering

I ordered 4 items online and paid with EFT, one of the items was out of stock but online I was given a date that it would be in stock. I arranged a delivery day 5 days after the due date of the late item to be sure it would have arrived. On the due delivery day I went on line and saw my order was due for delivery... I was very happy. Later in the day I dang to check my order was coming. I was assured it was scheduled and they deliver until 5pm. I called again to be told one item was not in stock and they had not been able to contact me! The lady told me the despatch lady had her coat on and was going home so nothing to be done, but call again the next day. I called early and was assured my order would be delivered that day.... 4:30pm I received a call the the van had broken down .... so eventually 3 item on the third day. Five days later I received an email explaining the refund process for the missing item and it would take 4/5 days. After 8 days I contacted them to be told they would send me some forms. I then received 5 forms to complete, they requested a copy of my ID, copy of proof of address, copy of my bank details, reluctantly I comp**** to be then told the refund would take 6 to eight weeks, it actually too 4 weeks. I had asked for the phone number and email if the CEO never came
