Same as all of the others unfortunately. I saw the very high reviews on Google but those are only for phone sales, not you selling phones to them.
They offered me £236 for my Galaxy Note 9 and when they received it they revised the offer to £100 saying the screen was very scratched and there was screen burn. this was completely untrue.
Use Music Magipie because they gave me £200 with no issues - beacuse there were no scratches on the screen and no screen burn. I've used them for years and never had any problems.
I have reported them to Trading Standards through the Citizens Advice Bureau, if you are reading this and it's happened to you then please do the same. I am also seeing if I can put a complaint in with TrustPilot as clearly the experience on the reviews page is not reflected in their very different high reviews advertised on their website.
