Service at its worst

Monday pass I contacted SIL for having no hot water at my premises.I received a call from the plumbing company to say they will come out to check I also mention they need to fone me 30min in advance it never happened.Plumbers arrived I had to stop my appointment.They checked eventually telling me some part needs to be replaced and the company will contact me the following day to give me the cost I told them it's fine dont worry about the cost get the problem sorted iL just pay there response were we dont have that specific part with us (wow)I told them fine let your office contact me early because there are no hot water since the weekend And that's the last I heard from the plumbing company.Im gonna try and be as friendly as possible because I'm quite ****ed off. Why are no one following up to find out if your client were sorted out with his problem. Are certain clients rated beacause of the area they live in if it's not upmarket you get treated like ****. Today are the fifth day without hot water does anyone care And lastly I'm not paying for any repairs after going threw all this ****. Claim nimber:20/079868
