SCAM: If I could rate 0 stars then I would!! If I could rate 0 stars then I would!! Trading in my 3 year old iPhone 11 which was in immaculate condition, it always had a glass screen protector and a hard backed case. There were no marks at all on this phone. Received a quote for £85 due to the condition of the phone. I asked giffgaff to send me the pre-paid postage in the post, which was made of a small cardboard cutout and a plastic parcel bag. Packaged the phone within the cardboard inside the parcel bag and shipped it at my local post office. 3 days later I receive a quote of £17 (!!!) for screen burn (!!!), which is not the condition I sent the phone in at all. The iPhone was fully working, fully functional with no issues, and I only traded it in due to needing the newest specs for a new career move. Seems like a scam on giffgaff’s end to con customers and not pay them what they deserve for trading in. Wish I read the reviews beforehand and went elsewhere. £17 and “screen burn” is an insult.
