Heartless, shocking service from a Wallmart company!

On 30 April 2020 I ordered a woodworking machine online for delivery as I wanted to get a home based business going to earn some sort of income while my businesses were shut down. I duly paid and received confirmation etc. When I realised delivery was going to take place from our local branch (Builders Express SouthCoast Mall) I decided I could save the R350 delivery fee and collect the item myself. I used the online "chat" service and asked the agent if it would be possible to change the order from delivery to collect. He said he would need to contact the branch and get back to me. On 12 May I received an SMS informing me that the order had been cancelled. This was followed by a phone call from Okkie at the South Coast Mall branch confirming "my" cancellation. I informed him that I did not cancel the order and could he please reinstate it. He advised me that he had received an email from head office advising him that I wished to cancel and be refunded and that unfortunately he had already processed the cancellation. He advised that I should receive my refund within 2 to 3 working days. 10 days and numerous emails later (stock, polite answers from Thobani Mnweba but no action) I still have not been refunded the R7498.30 I am owed due to an ERROR ON THEIR PART. Like all self-employed and many others who have lost their jobs I desperately need that money. I am now taking legal action. DO NOT order anything online from Builders! The only silver lining in all of this was Okkie at South Coast Mall who went above and beyond to assist me to buy the machine from them and still receive my 15% discount. I still had to do it online but waited in the store with him while it went through.
