Airtel — Airtel sim not working in UAE

Address:

Hyderabad, India

I came on visit to UAE and unfortunately I could not return due to COVID. My Airtel no. has not been working for past several months and repeated attempts to contact Airtel has failed. Customer service on phone was of no help at all. Network shows as no service even though it is postpaid and they refuse to hand over a duplicate sim to my husband saying I have to be physically present. There is no Airtel office in Dubai. This telephone no. is connected to several online payments and gas booking. Would appreciate your help in this matter.
