Shriram Chits — invalid sms notification on payment due

I have been getting messages to my number +91 9945*763 reminding of payment and referring me as mr. Ravikumar g, which i'm not the person that they are looking for. It is their mistake that without verifying the contact number of the person they have processed the payment and i have been victim since the time. I have been receiving messages since ages. I have complained about the same to your customer care still there is no action taken yet. These messages are nothing less than mental harassment.

Please help
