Bad website and lack of service

I tried to purchase a Swan Smoothie Maker online their website but their website crashed but I managed to get an invoice and then was told to pay this online by 2pm But this was not possible as their website was having technical difficulties so they failed my order, yet I was in contact with Catherine in Customer Service all day about this problem and I got the worst help ever! Merely a message saying we have ur order u just need to pay, yet I had been trying to pay all day and then for me to see this order is now failed. So I spoke to management who promised their is absolutely no stock left and if they manage to get me they will let us know! WELL to my surprise I find they are on sale again online, yet not a single message to me to say we have more stock would you like to buy this again and they didn't even let me know they were even for sale again! This is what I call shocking customer service! Do they even care about their customers! By the looks No. This is the worst online shopping experience I ever had!
