Reliance Jio Infocomm — not removing of router and refund of caution deposit

Address:

Plot No.614-B 51st Street 9th Sector KK Nagar, Chennai, Tamil Nadu, 600078

I am using the jio fiber from 27the august 2019 and i have paid a refundable caution deposit of rs.2500/- now, on 19.12.2019 i would like to surrender the jio router. Because they have not provided the modem for more than 5 months.

I regret to inform you that from19.12.2019 for more than last 13 days i am sending the mail & calls to customer service center they are simply delaying timing. But, no one has turned up for removing the router. I don't understand about the undue delay.
