Livpure — After submit the RO machine to livpureagent got legal notice after 2.5years

I used to live on rent. In march month I requested for dismantle through app of livpure. Engineer came machine handed over to the company representative whose information i got from livepure on message and the code. Then lockdown imposed I didn’t get any call nothing i thought its closed now as the one who took machine submit in the company but now after 2.5 year got a legal notice saying that I didn’t handover the RO machine. I mean livpure is asking after 2.5 years to submit machine. I submit it at that time only as one of the manager name Mr. jatin call for for machine i told him all scenario then he asked me to wait, there will be technical issue . Then I didn’t get call i thoughts its over . But now this legal notice they send me. Its not good.
