Makro online dismal experience - DON'T SUPPORT

I had a very bad experience with buying from Makro online. I bought Osram Night Breaker +220% H11 globes for R755 on the 27th of August 2026 at 3:02pm order number OD***. Paid via credit card and was promise delivery by the 5th of September at my home address in Krugersdorp. I've followed up by logging in today to find out my order was cancelled. I phoned their call center and spoke with Tabiso Botha call reference 3G1L8, he informed me that the order was cancelled by them on the same day due to not having stock available and that I can receive my refund within 14 days whilst their system shows it's available within 3 to 5 working days (discrepancy 1) whilst on the phone I went in on their site and saw that there was 3 of the specific product still available and I informed him of that. Yet he could not give me a valid answer why it shows 3 available and yet my order was cancelled (discrepancy 2). During my waiting period since the 27th of August, I have not received any communication and or notice of either the cancellation and or the credit that is due to me. I would never recommend buying anything form Makro and or Makro online. The service is dismal and borderline ******** if I don't get proof of my refund. It seems to me that their marketing is very misleading because it still shows that they still have stock on hand of the product that I need.
