Great I will check on that, I've already started the process for unfaire dismissal my soliciter has advised me to get more info on the problem with this job, I managed to dismantle 2 of them and get them out that way and I cut the top off the other 2 to get the head off then hammers a broken stud removal socket on applied lots of heat and a big bar to twist got them apart then managed to punch out the tips from the other side it sounds simple but it took me 4 days of heating and heaving and lots of swearing ha
