Makro Online shopping profile is not adding my items

I have been struggling all week with the Makro Online shopping platform. I called, emailed, chat botted countless times to the point my airtime depleted while waiting for over 15 min for me to be helped. I have several references and no one can tell me what my issue is with my profile or a solution. I have been using makro online for 2 months and now when I was shopping my entire cart got deleted. I try to add everything again and it's not adding to my trolley so my trolley stays empty even though it tells me product successfully added. I used different devices, my laptop, deleted the app and reinstalled and still the same. I signed out of my profile was able to add everything when I go to check out I had to sign in once I did that everything disappeared. I called and called the customer care they can't tell me what's wrong nor can they help all they tell me is that it's been escalated or someone from the relevant department will call back. This has been since Monday, today is Friday and specials are ending not one feedback from all the customer care agents I spoke to. This is horrible and I've been a long time customer always giving good ratings on my orders and deliveries. I am extremely disappointed and frustrated as I cannot shop with makro and no one is bothered to assist.
