Mate do it, get out. Back in the day when I did my initial grade 3, it took 6 weeks. I was there every day 9-5 (except weekends). We ended up logging 180 hours ground instruction, and the normal 50 hours flying, but the point being we were there everyday and working at it getting done. We had 2 and sometimes 3 instructors there to get us up and our flying hours done so that we could get our rating. Dont burn your bridges, get your training records and go elsewhere, thats a joke the way they are treating you.
