I used Martin and he was brilliant.
Passed his details on to a friend - had same experience as you - terrible.
He was on leave a bit and his locum was THE WORST.
We didn't have a great experience with Martin - he left on a two week holiday the week we were ready to exchange and didn't even tell us. His locum was ok. Overall I was very disappointed considering we had very strong recommendations.
I got a recommendation on here for Gisby Harrison as a conveyancer. Worst advice I have received. Use them at your peril.
