The next day on Tuesday 14.12 he texts me to say he has Covid and needs to isolate (very convenient). I said ok fine let me know when you can resume work. Hadn't heard from him so texted him today to ask when will he come back, he says he is in isolation till 26.12 (thought it was supposed to be only 10 days) and that will probably be sometime in the new year.... Again sent him a text asking for a definite date and his reply is 'lets say the 7th'. Is he taking the ****????? I want to sack him but paid him 80% and he was supposed to buy the window, tiles, switches and sockets, toilet and sink etc which he hasn't bought. What can I do? My wife and I are so stressed and upset, our lil kids are even more upset as our house is a mess and haven't been able to decorate it for Christmas.... Any advice will be much appreciated.
