I've purchased 2 items on my debit card that haven't turned up, I have managed to find out that the company I got them from are being far from honest about why my parts are still not in stock so I want to get my money back sharpish.

They took nearly £550 4 weeks ago and haven't sent me anything so am I entitled to a refund or can my bank deal with it ? I have a strange feeling even if I ask for a refund it will never appear so I'd rather the bank dealt with it.

Anyone know much about these sort of things ?
