LazyPay — Spam sms. multiple calls and harassment, threats

Have an outstanding balance with Lazypay . it is around ₹5000 . i have already informed them so many times since the beginning of this year that i will clear it on 31/01/2021 . they are still sending me Spam smses. they exceeded their limits when they sent me 30-45 smses in a minute. i have already spoken to so many collection agents since jan 2021 and have clearly told them that i will pay on 31/01/2021. they are still calling me and sending so many spams sms. the most atrocious incident was today when an agent called and kept on sending smses for an hour. in a span of 15-20 mins, that collection agent sent 550-600 smses. +[protected] this is the number from which i got. call. name is Rahul Tripathi and stays in Nalasopora. he abused me and threatened me when i told him i wont pay. and thats not it, he entered my number in various e commerce portals like flipkart snapdeal and medlife to send OTPs and harrased me. i told i wont pay as he was continuously sending spam smses . he harassed me by calling again and again and kept on sending smses. i would like to pursue this issue legally. i will not be paying anything due to this incident. i want to ensure legal action is taken against Lazypay and that collection agent too.
