See, on safer side take these actions:
You have to deal with it more for few months uptill your artcleship gets over as literally ICAI takes no steps in favour of articles against the members.
You maintain proper material record proof that you are taking your training.
And in case you wanna really punish the person as you are frustated this much, file a legal complaint in ICAI describing each detail (but with proof of misconduct) and if needed file an FIR in your nearest Police Station also.
Donot leave this profession bcz of such Idiotic creatures existing in our profession. From my experience I can assure that after completion of training and becoming a Chartered these things will not matter much and you will enjoy your profession as well as your life.
DONT SPOIL YOUR DREAM! BEWARE OF DREAM STEALER!
P.S- Even I went through some serious mental torture during my articleship but today I regret that I should have taken a bold step and filed complaints to both ICAI and PS as someone should stop this discremination!
