Nightmare of shopping with Zulzi

I placed an order and paid. When my order was supposed to be processed I was informed that quantities are limited to a certain number per order. This was only after paying. If quantities are limited then why are we as customers not informed about the limits is why is the app not setup to limit quantities? I called and was on hold for over 10 minutes but the call was not answered. I canceled the order and over a week later I still have not received my money back. I need my money please.
