Horrible snatcher

This was my first time buying from them and I must say I've had the worst experience and I will NEVER buy from them again and I'd never recommend them to anyone. I ordered 1item from them on the 25th of April. They say their order takes 10 days to process. Which is ridiculous, anyway after 15days I get an email that unfortunately what I bought is out of stock. Was given the option to either get a gift card or my money back. Because I'm so fed up with them and want nothing to do with them I asked for a refund. I sent them my banking details so they can process the refund that also takes Hella long days, till today I haven't received my refund. I don't know what system these people use that everything takes so long to process. And they will not respond to my email promptly, I don't know why they operate if they cannot deliver and attend to client queries efficiently.
