So about 7 months ago we hired a gardener to trim some huge bushes in our garden as they were getting a bit wild. He was expensive but worth the work and he cleaned up etc. He told us about a maintenance scheme that he does for €8 a month, which he thought would be helpful. (We have a completely gravelled and patio garden, no weeds grow in summer due to heat, all we have is 3 bushes)
We thought the idea was great as he could keep on top of the bushes. Fast forward 6 weeks and I was moaning to DH that gardener hadn't been and it was DH fault for forgetting to tell him we wanted him to come, even though he said he had asked him to come. Anyway we left it and thought we'll just do it ourselves after another few weeks.
So for the last 4 months or so we have been hacking at the large bushes and trying to keep them fairly presentable between us.
We just arrived home this week after 3 weeks in the UK to a letter through the door saying we owe him 7 months of garden maintenance 
I just think it's very odd that we've never once seen him (I'm a SAHM so I'm around the house a lot), nor has he ever left a card to say he has been or what he has done. There have been literally no signs that suggest he has been at all.
And the main point being what has he actually done if he's been??
DH is mad and says he is not going to pay him but he is yet to call him to speak to him.
Awbu to be reluctant to pay this man and would you pay him in the same circumstances?
