Eon blew up my computer should they pay compensation?

i was working from home the other day when there was a bang from outside and all the electric went off in my house, i went outside to see what was going on and eon had dug up the electric cables beside our semi house, in the rain i might add, i asked what was going on and they said they were fixing a reported fault, we have had no problems but they were digging right outside next door. from the hole was smouldering smoke and a very strong smell of burning. i asked why they had not informed us there was a possibility that the power would go out as i was using my computer at the time, they were very flippant and said the power out had affected the entire estate and that to inform everyone would have taken an entire day and they didnt have the staff to spare, anyhow long story short when i tried to turn on my pc the next day it was completely dead, i emailed eon and told them what had happened and that the power surge had burnt out my power supply on the pc as i was told by the pc repair shop and they have emailed me back saying thankyou for your concerns we have forwarded your email and someone will contact me in 10 days, however now it turns out that its more than the power supply that is fried but the mother board and something else, the pc repair shop are saying for the age of the pc it would be cheaper to replace it than to repair it, i also need to replace the surge protector socket it was plugged into as that is also fried. i cannot afford a new computer and i cannot afford to get it repaired and i need it for work, im a single parent working 2 jobs to support my kids, should i really have to be out of pocket for something that was entirely not my fault or should eon pay for a new pc? im using a crappy netbook i borrowed at the moment but its no good for work as its too tiny to fit the programms i need
