Airtel — refund of security deposit for disconnection of broadband

Address: 560061

I have disconnected airtel broadband on nov 8 of 2017. To refund 880 rupees they told they need 50 days. Even after 50 days, they are asking for again 20 more days to refund.

I lost patience as i have called and mailed many times to refund..

I think airtel is in debit... They need to pay loans to banks or what with my 800 rupees..?

Airtel is behaving like a beggar...
