IMEI listed as stolen
I Purchased a iPhone 5c off gumtree, I met the owner in person and the phone worked fine for 3 months until last weekend when I couldn't get a signal (just saying searchin) I took it to the Apple shop were they said they would change the phone as it was still under warranty. They did there checks IMEI and told me that it had been reported stolen how can this be when I've used it and it's not been blocke? What do I do can I get it unreported as stolen or have I got an expensive paper weight???
