Ssense / highly upset customer

I made my order and when I was about to pay something went wrong and I got an error screen. I wanted to pay via PayPal but for some reason I wasn't able to do that. I contacted Ssense and asked them for help, I explained that something was wrong with their payment system and they promised they fix everything as soon as possible and contact me back later with the results. I waited patiently but they never contact me back. I sent them a message but they did not reply. It seems that these guys were not interested. Well that's their way to do business, they just pushed away a potential customer. And I wanted to buy a lot of things from them. In my opinion this company isn't a good choice.
