......"Not my problem mate"....
I had to read this three times, I think the first couple of times I was in shock, then when it sunk in what had happened, I had to go and think about what to do. Whilst many of you would go down the legal route, which would be costly and still not give any joy at the end, I cant agree.
CJ this customer is a scum bag, I have not the slightest doubt that you are the first person he has done this to, and if it was me, then I would be engaging the 'services' of someone to go and collect this debt come hell or high water. However I would do this first, send a copy of your final account to the customer, registered post, I think thats the one where they dont sign it but you know it gets delivered. You know why I advise you to do this first dont you? yes of course you know why, I dont need to explain. I would not go to collect the debt but someone on my behalf, and someone who wont take no for an answer. Nip this in the bud now, and sort it out, from a distance ok?
Secondly the so called 'mate' I hope he rots in hell, and falls face down in the adhesive with his hands tied behind his back. Your life is better of without this two faced, schemeing, back-stabbing, jack of all trades master of none, and what goes around comes around, but it can take time. You have to much aggro on your plate at the moment deal with the scum bag customer first and then tackle the other one when your ready.
