Bad service

On the 25/07/2025 I ordered the nuts lock for my car and I was told I will receive the parts within 4 weeks. Then on the fourth week I called to find out if it had arrived. I was told it is discontinued and David told me to send my bank confirmation letter and ID copy so I can get my money back. On the 12/08/2025 I send him docs. On the 16th I called which was Monday, because David didn't not give me feedback when I called him on his WhatsApp number Friday and Saturday to find out why I have not received the refund. Then I spoke to his manager and they send me endemnity. And was told I will receive my money after 2 days this week. And today is Saturday still I didn't receive any update or my refund back from Renault Roodepoort branch.
