Airtel — incorrect billing, myapp not working & cancelled mnp request

Address:

713201

I have an Airtel postpaid connection for past 1years. Everything is working fine but for the past 3 months Airtel charging me an incorrect billing. Also, the My Airtel App isn't working and updating properly. I've raised complaints with the customer care number severally but no resolutions found.

Also, recently I've raised an MNP request on 18th of March 2018 to port out my number from Airtel Postpaid to Vodafone Prepaid. But, without any intimation, they have rejected it on 22nd March 2018.

This month also they have charged me incorrectly 700Rs. Which is not been cleared till now.

I just want to port out my number from Airtel Postpaid to Vodafone Prepaid.

Please help with this.

Thanks,

Prasenjit
