TeeFury review: they haven't provided the order and had too many excuses

I have ordered 4 t-shirts and presents from Tee Fury LLC. It was written on the website that their standard delivery took about 7 days. After 6 business days I got the first email, where the seller excused and asked to wait more, because they faced some unexpected difficulties. Ok, after another week I got the second email, where they found new obstacle and said that I needed to wait more. I already sent 4 emails and asked to return money back. I don’t want to deal with them anymore.
