Cars24 Services — Unnecessary calls everyday

Cars24 has made me realize that I made a mistake by sharing the mobile number with them.
I mean, there must be a limit to spamming too guys. !
It's been around a week and I get atleast 3 to 5 calls a day. I keep blocking every number but that's of no help.

Till a certain point, it can be called 'Marketing', but when you cross that critical threshold point, you are just creating negative vibes about yourself in the market.

Do something and add my number to the DND list. And make this DND process easy so that people can stop whenever they want easily.
