Livpure — Mental harassment post dismantle request for more than a year

I had rented a Livpure smart RO water purifier and was using it for almost a year until we had to move out from Bangalore on 10th August 2020. We have tried contacting Livpure customer support stating the situation of moving out well in advance on 28th July 2020(2 weeks time for dismantling). First of all the customer support agents were not responsive, unreachable most of the time though we managed to let them know also I have mail proof that stating clearly that after the mentioned date(10th August, 2020 - Attached email proof below) we will not be Available as we were leaving our rented flat so that they can collect the water purifier. Even days before leaving the flat I tried contacting also mailed them so that they can collect the water purifier stating clearly that after the 10th of August, 2020 we will not be able to help them with this as we Handed over the keys to Nestaway(we used to stay in rented Flat provided by Nestaway) and until this, there was no respond, service visit from Livpure and they didn't collect the water purifier.

Now it's been more than a year since we left the flat and suddenly I started getting random calls from Livpure stating they came for dismantling at my flat and over quite a few times I helped them as much as I could providing them all the contacts what I had of Nestaway people and owner's number as well. Suddenly it became Harassment to me getting calls, SMS every day for same reason repeatedly over and over again from different persons, and in the end, they started threatening me with a Legal notice(screenshot attached) which they sent me over my WhatsApp number and started Harashing mentally asking for 14, 000 rs with Notice.

It's a clear case of their mistake and carelessness of Livpure which has caused them this issue and for that, they can't Harrash me every day for the thing which is not in my Hand. I have helped them in every possible way that I could before leaving the flat on 10th, August 2020 even after leaving the flat even after a year sitting in my Hometown far from Bangalore. I want justice for me from Consumer Court on this matter, this Legal notice asking for 14, 000 rs and repeated calls, SMS from Livpure is Mental torture to me.

Attaching all the email proofs and legal notice below.
