Well I've defo not overcharged, £478 for 16mtr crmcs, with a small amount of levelling to do. I was a bit between 2 prices for this job as I wasnt sure on the probs I would have with a few things, usually if I'm a bit unsure between price I'll split the difference, here I was £450 or £500. Like my method?, lol.
I've been quite agressive with him so far and its not done much good. I did tell him last time this happened I ripped out the clients entire bathroom (I didn't and this hasnt happened before).
I'll pay the decorator a quick visit on monday I think, while he's at the property, will make him feel very awkward.
I'll be covering myself in future somehow, thats for sure. I've heard tales from plumbers before about not getting payed but never happened like this directly to me.
