I totally agree with Sarah,....mostly!
I simply would not go back, and then when they do ask why you haven't been back to clean their windows you can politely tell them that as you cannot meet their exacting standards you will not be cleaning their windows again.
DON'T TRY AND DEFEND YOURSELF!!
Absolute waste of time, smile sweetly and move on, never give them ammo to argue and get on their high horse.
If they moan at you say absolutely nothing, don't nod, don't make a sound, leave a pause of a few seconds after they stop talking, thank them for their past custom, wish them luck with finding a new window cleaner and either hang up the phone or turn and walk away.
you may want to argue and defend your integrity, but you will be wasting your breath.
their is nothing more annoying or frustrating than looking for an argument and not having the other person argue with you.
And it takes skill to do too.
Passive-agressive...ask ghandie
Be professional, being argumentative or verbally agressive will lose you more work, there is a guy in our area, he's an ok guy and a good window cleaner, but he has a bad rep cos he agues with his customers, and he has lost work as a result...and the stupid thing is, he doesn't even realise it...
doesn't matter how lucrative the account is, it's only 15 quid, every week that goes by you will pick up more than that.
and there is a certain satisfaction when they ask you to go back and you smile at them and say sorry, no thanks.
Make sure you warn any other window cleaners you talk to about them too
Halloeen is fast aproaching, and I really would not recommend paying some lad a couple of quid to go out and 'egg' their windows
I just have to say that cos it would be sooo unprofessional...wouldn't it
