L&t Finance — Harassed by SPAM Calls everyday

Hi,
I am constantly getting 5-6 automated calls everyday from L&T finance company regarding their personal loan which I never needed or ever enquired from them. I am harrassed with their constant callings and it has seriously affected my mental health as well. They should be penalized for this activity as I can see that lot of other people also are affected by their marketing approach on twitter as well. I have been constantly putting their number on blocked list but it's too much I just can't do this forever and L&T needs to STOP RIGHT NOW
