I had same problem with CASH4PHONES, I sent a brand new blackberry phone with screen protector etc..was quoted £65. Once cash4 phones received the phone,they say, there was moderate wear and tear and only offered £52.98.I accepted the £52.98 because I did not want them to return the blackberry in a damaged state.I did not trust them.It took aver a month to get the cheque.I was so anxious and stressed ,I could not get in touch with CASH4 PHONES by telephone or email for a long time.I eventually mentioned about talking to trading standard and sent them a recorded delivery letter requested payment,stating that they have breached their contract.I should not have been greedy and there was better and more reliable company offering £52..00 in the first place.I strongly advise people to be very careful before choosing CASH4PHONES.
