Consumer Redressal

Hi, I hold a AIRTEL 4G LTE connection (Number: 7760118110). There was no proper network coverage inside my home. (I need to come and sit in the balcony if I need to use the connection, moreover I am staying in a prime area called HSR Layout in Bangalore).After raising complaint also they didn't bother, so I decided to disconnect the connection. I raised a disconnection request on 23Jan2015 and got a confirmation from AIRTEL saying my request has been registered (Ref # 59981263). To confirm, I called on 30Jan2015 and they told that there is no such cancellation request. So again I sent a mail on 30Jan2015, I got a response from AIRTEL saying my request has been registered (Ref # 60083521). I got a bill on 04Feb2015 and I paid the bill thinking that they might have closed the connection. But on 11Feb2015 I got a mail from AIRTEL saying my Credit Limit got revised. Sent a mail to AIRTEL on 11Feb2015 and they created a can. request (Ref #: 60275946). AIRTEL need to waive the charge.
