Indian Railway Catering & Tourism Corporation [IRCTC] — Suddenly my irctc account is become suspended

I am Sambhu Nath Adhikari, have an irctc account (sam_adin) and usually whenever I/we wish to travel I had booked my railway ticket from irctc. I had booked three tickets on june for october 2016. Now from last month I saw that I account is suspended due to "Use of autofill Scripts or Enormous hitting on site". I dont know their error message and for what it is raise. Then I am asking several times to let me know the exact reason behind this. They told me to open a new account with new mobile number and new email account. This is very funny that it is not necessary to someone have more than one mobile. I heard that so many people having this problem. So as a consumer I want know what is going on behind this?
