Airtel — Someone Else's Bill Sent to Me

Address:

Airtel Lucknow

I am receiving internet consumption bill from airtel black since last 2 months though I do not have any active Airtel connection. The bill owner shares similar name as mine, however the other details like address and Father's name are different. Just because our names are similar, Airtel has picked up my mail ID and sending me the bills every month. I have written to them but even for March 2022 I have received a mail with the bill details asking for payment. Not sure how such a big mistake can happen. Please help in getting this issue resolved
