He briefly asked about my profile and preferred location and expected salary. Then he briefs me about the job offers available that machining to my profile and preferences and asked me to proceed with the first round of interviews.

Day*:- (**-Aug-**)
The person called me again and ask to schedule the round with companies HR. post completion of the first round HR advised me to get back to careerindex.co.in for further process by paying a minimal fee.
after call completion the first person from careerindex.co.in called me for the remaining process and assured me money back by paying ****/- Rs.

Day*:- (**-Aug-**)
After paying the required amount the person from careerindex.co.in schedules the technical round with offered company HR. post completion of the second round HR advised to take an aptitude test once it is complete you will receive the confirmation letter and face to face round details. for this process, you will be charged a minimum fee and the rest of the details will be handled by careerindex.co.in.

on the same day the person from careerindex.co.in called me and forced me to do a transaction of Rs ******/- by assuring the amount will be refunded after completing the interview process.

Day *:- (**-Aug-**)

The folk from career index. co. called me in the early morning to release the offer letter and need to pay *****/- for the process. which I have to refuse and told him to cancel the process and refund my money back to my account as I do not need this job offer.

Now he is not picking up the call for the cancellation process although i tried calling on the official helpline number of careerindex.co.in which is always switched off.

I request you to please file the complaint against the careerindex.co.in and help to get all money in my bank account.
