Airtel — airtel number porting issue

Address:

Elegant Embassy North, jakkur, 560064

On 16th-apr'19, i went to airtel office in yelahanka, bengaluru and raised the request of porting my number from idea to airtel. On 18th, i got the message that service has been reset but it's 26th, still network is not showing for airtel sim. Every time i contacted airtel (10 times), they raised a new complaint with different representative but no body has taken any action as of now. I have highlighted the same on twitter but no positive response there also.
Is there any way we can complaint somewhere where these lazy people should take some action?
