Sent my apple iphone 4 to them for £130, they claimed there were "lots of scratches on the back" (not sure how as my phone always had a cover), so suddenly the offer price of £130 was reduced to £78! Not quite sure why a few scratches would reduce a phone's value by £54!! Unbelievable. They then had the cheek to expect me to pay £6 return postage in addition to the £7 postage I had to pay to send the phone. I would be very interested to know how many phones they actually pay the advertised price for. Use at your peril.
I have since sent my iphone4 to Mazuma Mobile - they paid up fully the price advertised on the website of £100. No claims that there were scratches to the back of the phone that would justify a deduction in the price. I think that says it all.
