No physical receipt, no service

Bought items to a value of 23k+. The lounge light was missing 2 hanging items that I had to go back to the store to get. (Mind you, these were discovered as the light was hung). I had placed the receipt in a car that my wife used on the day where I went to the store. I asked her to send me a picture of the receipt. I took the card I used to pay. I had the app that reflected the amounts that were swiped in the store. You'd think with the invoice picture, we would be able to source the physical receipt from the system, if that's what is required to get the missing items. But the store turned me away, saying I need to either wait for my wife to return from her trip and bring the original receipt or recall the contractors to take the light down and source a bank statement so I can return the item. Spoke to the customer care over the phone while in store, and the consultant asked to speak to a colleague in-store, to which all declined, including a certain Mr Mdluli who is said to be the manager. Massmart must be ashamed to have such systems and employees who have no regard to customer experience. Systems are supposed to enable business service clients better instead of hindering service. My time and money were wasted and I regret going to this shop to begin with... Learn from the likes of CTM where customers matter!!!
