Airtel — mobile functions are not working properly

Address:

560067

I converted my existing plan to airtel 499 family plan on 19th nov 2019 and i have added my wife number as child number. After activation my number getting so many issues
1. She could not able to call outside karnataka std
2. She could not able to call international calls
3. She could not able to use internet using mobile data
After series calls and follow ups the issues 1 and 2 resolved. Mobile data issue is pending since 3 weeks. Initially it worked after resolving 1 & 2 issues mobile data is not working. We are calling almost every day, they telling some stories and i asked them remove the child number from parent, that they could not able to do that also. If they are not clear about the plan i don't know why they are imposing on people.
They are not doing any follow ups and we have to call them and explain the everytime from the begining.
Thanks & regards
Ravi
