Possible scam of course

Hy, I was on opencv university webinar where Mr. Satya Malik presented a course pack for a very good price with high discount. After the webinar I had incoming call sms and email from Srinjoy Mitter. Today I contacted with him over phone, and he offered more discount for course. He sent me email with registration and paymant link. The link not an opencv.org link. Could you confirm Srinjoy Mitter working with you as program advisor ? The lots of email sms and incoming call is made me unsure that it might be a scam and they had somehow obtained my contact informations.
I saw an other forum post with same story but an other advisor name. Administrator said that absolutli scam. What is your oppinions?

This was the last email from him:
