Hathway Cable & Datacom — harassing and disturbing customers with the "legal term"

I was using this hathway in bangalore, in dec month beginning i told them that i won't be in the country after december so please come and collect, but they never showed up. Now after 3 months, they sent a mail telling "legal action will be taken if i don't return the modem" i called my landlord regarding she said some hathway guy came and took that modem thing"

First, i had given 30 days time to come and collect. Why you guys didn't show up? Check call records for the same.

Second, do you expect me to stay in bangalore till you guys come and collect?
