Nightmare website and customer service

I don't understand why Wellness Warehouse cannot sort out their website!! I order online and it's impossible to use one's loyalty points. One is unable to call them and when you email they may take a few days to respond. My latest experience with them, they haven't responded at all!! What is their problem? A big company like this - 4 years since Covid and people are ordering far more online and one can't order from them. They are a total nightmare!! Apart from the fact that it takes a week to receive the goods. In other companies, one gets delivery overnight or at most 48 hours later! A huge thumbs down from me. I had just started using many of their own products. I have ordered the same supplements elsewhere - other brands and saved myself a few hundred rand.
