I received a good offer in the summer (end of July) from a company, so I resigned from my current position and after that, on the same day, talked to the CTO explaining him my leaving.
End of July, the same day:
He insisted I shouldn't leave and we should meet after work to discuss the matter further. He even went to HR and told them to put my resignation on hold.
Later that evening he talked me out of leaving, he said if things don't work out he'll recommend me to his many connections and finally made me an even better offer than the one I had received. I accepted it and told the other company I'll stay where I am. The CTO said he'd have everything done beginning of September as he was gonna leave for holidays.
Beginning of September:
He came back, he said we'll do it beginning of October. I wasn't really worried as I had a 3 months notice period so I wasn't gonna join the other company before 1st of November had I left my current one.
Beginning of October:
I spoke to him again and he said it would happen beginning of November.
Current situation [2nd week of November]:
I've talked to him about the situation about 2 weeks ago and he said I would get the new contract last week. I have seen nothing meanwhile.
Now I can see where this is going and would probably have to leave.
I am looking for advice on how to proceed in this situation?
