Airtel — airtel plan and service

I am having 4 postpaid connection of airtel and want to port them because of worst service of airtel. And they are not allowing me to port because of their technical issues and stop my data connection also.

Worse service provider in telecom industry. There site is always having problem during payment and asking me to do payment on time and stop my data plan.

Not advising customer about their issues. I was one of loyal customer with them having all my family numbers of airtel. You dnt value your customers, then we have much more option/ be sticked with arrogant customer care persons who doesnt have the sense how to solve customer complaints.
