Hathway — Issues after disconnecting my connections

Hello,
I closed my Hathaway connection due to my layoff. i am from Nagpur and I have taken the connection in noida so now I left noida. Now the issue is they are saying give back the router so I could not give return back because I left Noida so I am saying to them take a penalty from me. so they are saying 2500 rs. for the router. and its huge amount as I said due to locked down, i lost my job. so i don't have much money or if you can give me a model number of their router so I can purchase it for you, but they said no company don't use any other router so I said ok no issue so just give me a discount I can't pay 2500. and I as from my knowledge router cost is too huge normally the routers price are 1000 to 1500 Rs.
