Ive had this many times. I never show that im bothered and am still polite and i say no problem ill see you next month. You dont own them they can do whatever they like!
The one thing that really annoys me about peoples posts is when they say JUST BIN THEM or CANCEL THEM.
Sorry jdemarco,
I strongly disagree with your post.
Okay, we don't 'own' our customers and they can do what they like with regards having their windows cleaned, but what upsets me is that we have a verbal agreement - terms and conditions - which we should both adhere to, as close as possible.
If I told a customer I'll clean their windows once-per-calandar month for £X, and they agreed, had them cleaned and then started messing me about, I'd drop 'em on the grounds of them breaking our verbal contract.
I've even printed this on my stationery; my customers know and it's very VERY rare I'm asked to give them a miss.
My advice is to drop bad customers straight away - if you have enough work. And if you don't, drop 'em when you do.
