Update: Yes Securities was successfully opened by Thursday. It seems that Omni is some other Demat account also run by Yes Bank. Yes Stock trader is the app we have ti use if we opened a Yes Securities account.
The Customer care seems excellent for the Securities Account.
I also did receive a Virtual RM. He seems good and the first thing he told me was about the Yes Rewadz. He told me that I would be points worth 2k inr. I am not sure how or when since I did not get them. He told me that it is visible to him and will be credited by the 10th of Next month.
I was going through the Yes Rewardz portal and it seems that customers need to maintain 10k MAB to be eligible for this new account points accrual.
So, I would recommend all of you who opened an account to try to maintain at least 10k MAB, do IMPS transactions, use the DC at an ATM and make a transaction or two to get the full rewards. More details are available on the Yes Rewardz Website.
