Need help

Heyy guys i want to enroll in the fts test series and they're saying 7k. Like a lot of people from aakash institute have called and they're trying to tell me to enroll also they're saying that they'll provide additional discount if i gave psid and receipt of any of my friend who is also enrolled in fts. So it real or fake ? Should i do it. If yes can anyone pls help me in that can that i can get some additional discount?

Please tell me if it's scam or it's real. Should i also visit branch before enrolling online.

Please help. Thanks
