I had one too.
Quite a big place was inside and out every 8 weeks, all agreed she said yes please bla bla.
So I go to book in the next clean (this was a few months ago) she text back 'No thanks we are going to use someone else this time'
And I know who did them and why she chose them, because they were CHEAPER! And these are people paying about £10k a month renting the house!
So I said ok but what about our agreement? No reply.
2 weeks ago I get a text 'Can you come and clean our windows please ASAP'
I replied and said 'I thought you were using another company, that's why you cancelled our agreement?'
She said 'It didn't work out, do you want the job?'
I thought about it, after all it was a £240 job which two of us can do in about 2.5 hours.
I replied 'No thanks, as explained before we can't service irregular jobs. Also we made an agreement and you went back on it. We have approx 350 regular loyal customers who are our priority'
Loved it and I couldn't flounce because I was texting so I very 'camply' cast my phone aside
