IDBI
Not given job because of familyway

I cleared the interview for Executive in IDBI (july 8th at chennai). They sent me to the medical test. That time I am a pregnant of 2 months. So they stopped my joining process and informed that I may get the joining process only after 6months after my delivery. They told I may get confirmation letter reg this within a week thro' post. But I didnt receive any letter and no response when I contact them. I dont know what to do furthe
