Marko website problematic unable to pay for online orders

I am not able to order through the Makro website or app. I called Makro and spoke to an agent called Thabo who was unaware about the problems with the website. I'm not able to pay for my order as the message 'failed to pay' shows up.

I sent numerous enquiries via the website and Facebook page as I would like to order my goods. It's the first week of Black November and I plan to order every week. How can this be sorted out?

Two weeks ago I received an SMS from Makro about an order of 15th September which I had collected and signed for, yet on their system, it showed that I had never collected it and it still reflects on my online profile as in progress. This was never rectified despite speaking to Sibusiso Logan Gaula.
