Refund refused & *********** staff - Leroy Merlin Nightmare

I would highly advise anyone to not make any purchases at Leroy Merlin , most especially their Greenstone branch. On the 24/11/2020 paid for a Patio set from Leroy Merlin Greenstone. As they did not have enough stock on the day , their sales consultant advised that I should come back next week when the stock would eventually arrive. Unfortunately the *********** consultant took my details , but didn't provide me with a collection note. After a week I realized that Leroy didn't contact me to make collection , and so I showed up at there store a week later to finally collect my patio, set. After providing them with the invoice and receipt from the purchase , they told me that should have been provided a collection note . I told them that on the day of purchase no collection note was given to me from their consultant and I didn't collect on the day as he advised us that stock had finished. So I reiterated to them that I need my patio set today. They then told me , that the store still did not have stock of the patio set I paid for a week ago , so I requested that they refund my money. After-which I was given a purchase voucher (credit note ) in order to refund my money. I took this refund voucher to their cashier, and their store manager arrived and advised me that , given the high amount of the refund , they would have to investigate the matter before they could consider refunding me , even if the fault rested with their consultant who did not follow proper procedure . Of which should be easy , right ? • As they would just simply need to check their security cameras on the day of the purchase they . Which they would notice , that I had left the store without my patio set . • Or Alternatively they could check their warehouse inventory and clearly see that no collection was made or signed against , for my rightful patio from their warehouse. It is quite clear to see that Leroy Merlin does not properly train their staff . As yet , it is nearing 2 weeks , and still I have not patio set or refund . I am just constantly told that the situation is still under investigation. To say I am disappointed with their service is an absolute understatement.
