I posted a working handset to them and then had no reply from them for a month!
I contacted Mirror Go Green and they said that mt handset wasn't working and it was worth nothing. It is perfectly possible that it had suddenly stopped working (although I don't buy it) but my problem is that they didn't contact me to tell me this and when I asked for it to be returned to me so I could send it to another recycling company that would give me money for a non working phone they refused.

Crap customer service, rip off merchants.
