Blatant incompetence and no care attitude

Ordered items on 15/04/2025. I was contacted a day later and advised that one of the ordered items was not in stock. I requested that the order be cancelled and refunded in full. Received confirmation of cancellation and refund email on 17/04/2025. The refund has since not been received. I had liaised with a certain CLAUDETTE MASOKOTSO (who is a Manager in the Supply Chain Dept.) and she assured me that the refund was effected and I should check my bank statement. I have since checked my bank statement every day, and nothing still forthcoming. I sent the proof with the said Manager, who advised that the matter was escalated to the Accounts Department. A week later, still no response nor resolution and my latest email was blatantly ignored by her and her entire team. Should I not receive the refund by next week, I will hand this matter over to my lawyer and Leroy Merlin will be accountable for legal fees. Enough is enough. This is not rocket science....its just a few clicks on your system.
