Airtel — airtel postpaid service

I have tried to change my airtel postpaid plan for like 5 times still it hasn't changed. I event went to airtel store and they told me that my plan has been changed and it will be applied from when this billing cycle ends but it hasn't changed yet. Now I have 40 GB data still they are producing a bill of 955 Rs. which never goes up above 400 Rs. and from 955 Rs they have applied 500 Rs internet charges even when I have a balance of 40 GB data in my account. Their customer service is worst in the world. Their executives are so clueless, you ask them something and they tell you something else. For each and every issue they only say it is in process and it will be resolved in 4 hours. and Like it wasn't enough their network sucks.
