Defective items, refund delay and poor service

Apparently I should've checked HelloPeter before ordering from this company. On 8 October I bought a gaming monitor from Leroy Merlin, it was sourced from RAION Connect. The first monitor arrived with a hole right through the packaging and screen, it took days to collect with me having to follow up all the time. It was agreed that the monitor would be replaced, the second monitor eventually arrived and was defective as well. It also took days to collect, after I was first told that I must take the brand new monitor to the Johannesburg test centre for repair. I obviously refused and Leroy Merlin stated that they are not willing to send me another monitor of the same and will source an alternative, this didn't happen. Eventually I gave up and requested a refund, which to date, I still haven't received.
