Unfortunately, still haven’t managed to get a reply - paid for the diff on 18th December, my own is on the way out. He did come back to me on 27th and said he’d sort it out but silence since then - very poor form especially as he knows I’m stuck for it.
In the interest of transpareny, Dave contacted me a short while ago and issued me a refund - just wanted to be fully fair. Still need a diff - cheers folks
