Insult to injury

I got a lovely message from Irish broadband today telling me they have had "problems with my payment" so i shall be internetless for a while, this on top of the fact I have injured my knee in a most inconvinient manner, leaving me on crutches and in bed mostly....
Fun times for all

I also had to miss my first day of work today so...i think there is some phrase about problems coming in groups..too injured to remember
