Livpure — RO Water Purifier with machine number D1JW73D1002644

I used their service from feb 2019 to may 2020 and i was thrir valued customer. In june i asked them to dismantle the RO as i was planning to leave delhi in 15days and they didn't respond. I tried mailing them and called them regarding this multiple times but they were very ignorant regarding this. I even asked the guy who used to service it for them to take it off and have it with him so that in worst case scenario he will be able to return it back but they were simply not interested in taking it back. After leaving delhi i asked my security guard a favour to handle machine for 1 month more and promised him that within this 1 month it will be picked up by the company. But after registering the complaint in june the first time an engineer had visit to pick up the machinr was in oct 2020i.e. 5 months after the complaint. And it's obvious that as a customer our duty was to inform them prior to leaving the place which we did. Now recently i have been given a legal notice regarding this for 15k machine and 6k in subscription. Someone please explain why do we have to carry the burden of their mistakes. Recently i had a call with one of their executive and tried to explain them all this and his reply was sir hmari galti nai hai aur company paise to leke rhegi machinr ke. I mean what's wrong with them.
