Airtel — airtel sms services blocked

Address:

400078

Hello sir,

I have upgraded my airtel sim to 4g sim on 16th september 2017 at the airtel gallery. After upgradation my sms service are blocked.
My most of the banking services are linked with sms.

When i contacted airtel customer care on 19th september they told me to wait 48hrs your issue will be resolved then i call again on 23rd september same answer i received wait for 48 hours your issue will be resolved. So i call them again today 26 sept 2017 guess i got same answer wait for 48 hours
Its almost 10days they cannot resolve the issue. They don't know the reason why it is not unblocked.

I think airtel must understand what happned when sms are blocked. Instead of giving big advertisement on "airtel ka promise" they should first work on ground level which is completely empty no promise only 48 hours

This is very serious issue mr gopal vittal. You must take it else people will start moving to other service provider
