TCS iON — harassment by tcs employee

Dear sir/mam
There is a college at himachal pradesh named as himachal institute of engineering&technology shahpur tcs conduct exams here from 2012. Here most of the time mr. Ashish dhiman will be the venue head from tcs side and he tries to harass each and every person in the college unnecessary, he always tries to blckmail college employees while saying that if you are not doing this work we will blacklist your center name and no other exams will further conduct at your center. Some times when he is not available in the center everything goes smooth and no problems occured. While making such a non sence statement our team weakens all the time and thus this will create too much panic in our center unnecessarily. I request your team to kindly depute some other venue head so that everything moves well.
