I have received SMSes presumably from the Income tax dept asking me to file for taxes(please refer to the attached screenshot of SMSes). However the PAN details, name & amount quoted in the messages are not mine!! It seems like someone else's warning messages have been sent to me. I have filed and verified returns for AY 19-20 and paid taxes on my capital gains transaction on house sale pertaining to FY 18-19. The status of those returns also shows "ITR Processed" and I also got an intimation u/s 143(1) via email & SMS which said there are no issues.
I also tried checking any outstanding demand or notice by logging into both the online portal and the insight compliance portal but there were no messages anywhere. Also I have not received any notice by email.
How do I tell the IT department that they are sending me notices that are actually intended for someone else?
