Jamie, you may be doing a brilliant job as a lot of other couriers do and for that they deserve all the praise due to them, but if they cock up they deserve to be criticised too, we all make mistakes and are effected by outside influences, that's life but you blaming in part the knock on effect of being held for 25 minutes when you may have been a day late at times.
Delboy waited for 3 days on you and still not sure if you turned up at all, yet you still blame fanciers, of course you don't like negative feedback on an open and public forum but unless it is a lie you just have to accept it as the truth and part of what happens on any forum :-/
