Have had 2 decorators in the house all week and they finished today but I was out and he said he'd text me the total price tonight.the labour was pre agreed and was £600 he did a bit extra and has said now £800.This is a bit cheeky but it is a top job and tbh cheap for the finish and standard.I am over the moon with it BUT I asked him to bring the receipts for the materials and he sent me a text with the cost and said he has no redeipts as he has an account at the shop.What he didn't know is that I have been renovating houses for years and know the cost of evrything but let him get it as I was carless and he has a 25% off account.the figure he has quoted me is double what they actually cost and I have told him to go to Brewers and ask for a written receipt as they know me and will do it (I have spent ££££ there over the years)He says no and he will be round in the morning to be paid.i am on my own here dp working so i have said i will give him 800 and he can get the receipts during the day and dp will pay him tomorrow evening.he is fuming but what can i do?
