I disconnected my Nextra broadband internet connection about 3 months ago, they told me they will collect my modem and will refund my security deposit of Rs 1500, I have called them more than 20 times and also sent them mail, but no action has been taken regarding the same, every time they just say we have forwarded your request and will contact you soon . According to their company's policy, they told me they will disconnect in 30 days, but no one is paying attention towards this matter .
