My tumble dryer broke down in December, we worked out what the problem was and ordered the part on-line but because of the Christmas postal problems we didn't get it for two weeks, on Christmas Eve. 
My dishwasher broke down the week before Christmas, man came to fix it and said he couldn't get part until after Christmas, we watched him order it on his laptop.
Christmas came and went and after a couple of weeks we tried to contact him despite leaving numerous messages he never got back to us and eventually we called someone else out who said it wasn't worth fixing, get a new one which we did.
Argos came to deliver new dishwasher but we were unable to disconnect the old one so both were left in the middle of the kitchen, we had to get plumbers in to disconnect the old one (which is now outside the back door) and had to install the new one ourselves.
During the coldest week in January the boiler stopped working,it was freezing!
We have a maintenance agreement with British Gas who said it needed a part and they couldn't get it until the 10th of Feb, over 2 weeks away. on the 10th of Feb they phoned to say that they couldn't get the part and quoted me an astronomical figure for a new one. 
Needless to say, I got another firm in and arranged for a new boiler to be fitted yesterday. The night before the plumbing for the dishwasher & washing machine came loose and we had a flood in the kitchen.
It was a big job getting the boiler fitted and they had to call an electrician out after cutting through a cable but we are now the proud owners of a new boiler.
But, when I went to cook dinner the electric oven was dead and when DH went to plug the dishwasher back in the extension cable blew up leaving DH with black hands and a shocked face.
I'm afraid to say I've cried and shouted at DH who has been most sanctimonious telling me "as least nobody's died".
I know he's right but IABU to have had enough?
