Worst service delivery from Lifestyle home

I have been receiving the worst experience with Lifestyle home. I placed an order with them last year around November and the sales consultant told me that my order would be ready end of Feb or beginning of March. My order was only ready and delivered 30th of March, this is after I did a couple of follow ups with them. My order was missing items which I immediately notified the group about and there was a whole back and forth about my order details yet they had my invoice. Naomi than called and told me that the missing items will be dispatched and delivery would be made. I have been trying to get an update on this on all platforms with no luck, all the different numbers they use are not being answered and none of my messages are being returned. Yet I've fully paid for all my items which are not in my position.
