Following my email sent on 25th
Received log book today.
They printed it on 27th
I did give them 14 days and told them they shouldn't be faffing about with 2nd class post and enclosing 2nd class return envelopes.
I also said that they have asked me for same info again and are taking the Mickey.
They used first class post this time.
So emails do work folks. I did ring them up ten minutes later and asked them If They received it. So i am guessing the dead beat that confirmed the email opened it and actioned it straight away.
In future i will always enclose a copy of the BCA invoice to speed things up.
