I had the same untrue claim of screen burn when I sent my phone in in prefect working order with all original accessories and the box. MM did not meet any of their claims of terms. After waiting a week with no payment and no contact, I emailed them and they came up with the fake reason. After that in the same afternoon they sent me a sly email saying if I did not decline their offer of £30 for my phone within the next 2 hours they would do the £30 deal anyway. Their online offer was £130. These guys are scammers avoid ! When I eventually received my phone back i did a download test for screen burn and it was BS, but I already knew that. £30 for a premium mobile OYB MM !
