Oil Technics Ltd

I was offered a job with Oil Technics and I told them I was interested but wanted to attend an interview with another company the following week before I confirmed my decision. I did this and accepted the Oil Technics position 12 days after the interview. 2 days later I was told that they had withdrawn the offer because I hadn't accepted immediately! They then re-advertised the position so they didn't appear to have an alternative candidate available. The recruiter I was working with said she'd never had this happen before in 10 years. If they behave like this, I think I dodged a bullet!
