Plumber quoted for two days work, lots of different tasks including connecting up several fittings and running new pipework.
He worked one day, didn't finish the whole job, and got something wrong so dh had to redo some work and then finish off the job.
He has now invoiced for the full amount.
Dh doesn't want to pay full amount as it just wasn't good enough and he spent half the time quoted for here anyway. So he offered him one day rate. (the rate is all laid out on the invoice for each day)
Plumber chap not happy with the situation and so has come back to say it was a long day with no breaks so he wants that reflected. And also it will take a few hours for him to sort the building control paperwork for the job as it included wiring in an extractor fan. He will do this from home and that is why there are two days on the invoice.
Dh offered him full day rate plus a pro rata amount extra to reflect extra long day (he was here from 10 to 6).
He then comes back to say also we need to add 20%onto the whole bill as he has to pay the person who gave us his number a fee for matching him up with us. I have never heard of this arrangement before and I don't think it has anything to do with us.
I think he is a cf.
Are we being unreasonable or are we right to be quibbling this?
