interesting replies everyone

my main point was not so much losing the customer (i have lost and gained 100s over the last few years) but the lack of explanation
now dont get me wrong i love wfp......BUT :

the thing i dont like about it is you cant see the finished result when you walk away like you can with trad,so you have to trust the technology to work
given this i now find that being dropped for no reason does tend to put me on alert
simply because i want to rule out (lack of)quality as a cause
anyway taking neil williams advice about not knocking on the door i just put a flyer thru with this note on the back
dear .........
i am sorry that you have decided to cancel
i hope this was not because the quality of
service was poor,if so please feel free to phone
and i will be more than happy to try and rectify
any problems.If you have other reasons for cancelling
then i would like to thank you for your past custom
and wish you the best for the future
bit cheesy i know but this way i am being polite about it, and i do nearly every other house on this estate so they all know each others business, personally unless the pole is playing up i could not give two fishes teets about why they dont want their windows doing
