They advised me that work for FTTC on 20th September. Nothin has happened. So will I have to wait longer or are they just making lies up.
I think you're being a bit silly there and taking things too personally. BTor don't have enough interest in you to want to lie. They gave you what they thought was a likely start date. And it slipped. Welcome to the real world and the difficulty of managing large and complex projects.
