Unfortunatley you are allways going to get something like that happening now and again, You did the job right who knows how you might gain from it in the future.
I did a new clean last week. The previous month I spoke to the lady of the house as they had just moved in. They had not been cleaned for a year. Told them the price, upvc with leaded glass. £14.00. Bit expensive she said leave them this month but clean them in November.
So I cleaned them last week, Worked really hard to get them spotless.Left a card. The following day her husband rings me up. Who told you to clean our Windows?
Your Wife Did.
No she NEVER DID.
Look I am a busy Fella, I will not clean anybodys windows unless they say I can. Your Wife said to clean them in November, I have.
No she never, She said she would think about it. We have. You are charging an extorinate amount of money. So we dont want them cleaning.
In the end I had to accept they were not going to pay. He refused to pay.
I said fair enough, Enjoy your nice clean windows, they do look good dont they. But if you ever ask me in the future to clean them, You will have to pay me double for the first clean and you will have to pay in advance.
Its only £14 lost, Nothing to get uptight about.
