Airtel — broadband not deactivated since months and they are asking for payment!

Address: Bangalore, Karnataka, 560075

Website: www.airtel.in

After applying for a new connection (Application number rtblr7341882) on 23rd june 2017 and making 3 months payment of rs.2585/- via the website (Cheque/ ref no. 990631) they said it is not possible to activate due to technical reasons on 26th june via calls and emails. We initiated refund request - complaint number 89700882.in the meanwhile, some airtel agent called suresh activated the broadband on 30th june. But after 3 months bill generated was including the rs.2585/- that was already paid. When enquired customer care via lots of calls and emails they said that they never received the online payment - which was done on their website! Even after giving the reference number and showing bank's transaction statements. While doing these calls they removed the connection from home but did not deactivate the account and the bill now is still getting generated with 1-month extra amount even though we are not using it anymore. All the time getting calls from customer care to make the pending payment but nobody is giving the refund of the first payment of rs.2585/-. After calling for 47 mins and explaining the problem one of the customer care agent just put the phone on hold and went away. Called to so many other customer care agents but they redirected to seniors and after explaining the problem to everyone they just redirected to customer care number [protected] again. There are no branch offices in bangalore only stores who are not able to help and asked to call customer care. There is no option in website to deactivate the broadband connection like how other broadbands provide. Please help.
