Poor Service - Online Order

My recent online experience with Leeroy Merlin has been unsatisfactory. The anticipated delivery date for my order was not met, and subsequently, the order was canceled due to insufficient stock. The delivery did not occur within the projected timeframe, and no communication was provided regarding the order's status. My attempts to resolve the issue by contacting the call center on three separate occasions yielded slow and unhelpful assistance. Representatives indicated a need to liaise with the Centurion branch for order follow-up and promised a callback with an update, which was never received. Feedback was only initiated after I requested to speak with a senior staff member, at which point I was informed that the order would be canceled and a refund would take 7-10 days to process. It appears Leeroy Merlin requires enhanced staff training in online order management, as current practices are inadequate and pathetic. Despite my order and issues surrounding supply, the items I purchased remain advertised on the company's website, indicating availability in all of their branches. However, the company feedback to me is that they are out of stock and therefore unable to fulfill the delivery.
