I got to this site via a price comparison site. Cash 4 phones gave the highest quote so I chose them.
They were very quick in sending me the return envelop and sending me an email saying they have received my phone and that I should get my money in 10 working days. That was Nov 22nd and I never received my money.
The site doesn't work anymore and they never replied to my emails. The phone number is a recorded message asking me to leave my name and phone number.
They offered 118 pounds for my iphone 4 but never paid me. Total scam!
