We had a plumber doing our bathroom while we were away on holiday, he should have finished in one week but took over a month, wanted more money, and eventually walked out on the job (long story...). We had to take someone else to finish the job. One of the things the plumber wanted more money for was the fact that he had to employ a labourer to help sort out 'unforeseeable' wood rot problems. He told us that he used the advance money that we (foolishly) paid him to pay off his labourer, and that he was out of pocket as he had nothing for the work he himself did so far, so could not continue until we pay him more money.
This evening a man showed up on our doorstep, we were not at home so he got our mobile number from the girls and called me 10 times in total in just 15 minutes saying he worked in our house with the plumber and demanded to be paid. He went into long description of the hard work he did and kept banging on about 'you owe me money'. I tried to explain to him that (a) I don't know him and didn't ask him to do anything, (b) he should go to the plumber who employed him , not me, and ask for his pay, (c) at any rate the plumber told me that the labourer was paid.
The guy wouldn't have it and while not directly threatening, he said things like 'you don't know me' and 'I won't let this go'. I was upset at the fact that actually came to our house and told him that he is totally out of order that he came to the house and spoke to the girls (albeit over the intercom as the wouldn't open the door). He finally sent a text message saying he will wait 'until Friday' - not specifying what will happen on Friday.
I am considering going to the police tomorrow and file a complaint against him - problem is I only have his mobile number and no other details. I don't know the guy, don't know what he is capable of, and I am definitely not happy with the idea that he might call again at the house, especially when I am not there. I am not afraid of him personally, but am worried about the family as I can't be at home all the time. Even if he does not actually do anything he is harassing and intimidating by his presence and phone calls - my wife is shattered. I don't think I legally owe him anything, I believe he knows this but simply trying to intimidate us into paying because the plumber did not pay him (the plumber told us a pack of lies throughout, so not impossible that he said he paid his labourer but didn't). But realistically I think him and the plumber are in this together.
Any suggestions or comments regarding the above, the legal status of things, and to what extent can I expect sympathy from the police? will they look at this as a private commercial dispute and not get involved, or will they actually see the distress this is causing the family and take some action? I am London so it is the Mets.
