Airtel — Sim card stopped working in the UAE network

Address:

N-19,N-19,AL AMAJID ,AL RAHBA,ABU DHABI,ABU DHABI,United Arab Emirates,840

I tried to contact via customer mail but they are sending me reply that my mail id is not registered with my cell number (+91 [protected]) there is no customer care number they provided and they are also not taking any request from there Airtel application simply they send error message. I want to resolve this because I couldn't receive any OTP SMS from any bank so I’m unable to use any bank services for any type of payments.
