Livpure — Mental Harassment post returning the product.

I initially requested to rent Livpure last year during the first lockdown was imposed. The product was delivered but it was not installed. In a few days my company allowed me to work from home and I planned to leave and move out of state to my native town and informed Livpure customer support to pick up their product. The product was not even opened from the box as no one had arrived for installation. There is a screenshot of the the conversation with their support representative in their support portal page. They delayed sending the pick up party for over 2 months, however they did refund my booking amount of Rs 375. Later one of the pick up representative called and picked up the product and I dropped the reply to the support representative that the product has been picked up.
After few months I got multiple calls/SMS from other Livpure representative arriving to pick up the product and in each case I informed them that the product has been already been returned and shared the pick person's phone no. Now recently I received some legal notice saying that the product was installed at my home and subscribed and I have not been paying the subscription amount for months together. And they are asking for me to pay the cost of the product with all due amount including the costs for legal proceedings.

The product was not installed in the first place and their pick up person has already retrieved the product.

Attaching the portal conversation with Livpure support person along with the legal notice which was sent to me.
