[mothered]

an FTID done thru this returner not me (Royal Mail) - the tracking info shows "return to sender. The recipient has refused to accept it". I don't know what he did to the label and he's not replying to me.

This Is the second post I've read today of the method failing.

Of course he's not replying- the flawed FTID has (unsurprisingly) failed and unfortunately for you, he's disappeared with your cash. A lesson learned - stick with the traditional methods.
