Online order poor service

I recently made a Makro order for pick-up on 25 Sep 2025 and when the order was placed, the order was supposed to be ready on Sat 27 Sep 2025. Can you tell me why pick-up was extended to 12 October????? Their customer service is so poor. Their customer representative cannot provide any information or reason for the delay. I am so frustrated with Makro's poor customer service.
