I purchased a bostitch nail gun from Toolstop in May of this year. It is firing 2 nails together and keeps jamming. I have contacted Toolstop and they have told me I have to send the gun back to them. As you can appreciate it will cost a lot of money to send it back to them so I was wondering if there is a place you could recommend I take it to. I live in the West Midlands. Regards Mrs A Eley
