Kotak Mahindra Bank — Stop sending me SMS

Hello Kotak Mahindra Bank,
Stop sending me SMS for opening a account with no maintenance fee. I have never subscribed to your bank but you guys are annoying me by sending frequent messages. It's kinda getting worse. Daily I get 2 3 messages from your bank and there is no option of blocking the messgaes. You guys think this is your marketing strategy. Even if people are intrested but you annoy them with this many spam messages they change their decision and i will also suggest them not take any account from your bank. I need to stop getting messages from your bank ASAP.I don't want any account in your bank nor messages from your bank.
DO NOT SEND ME MESSAGES.
