Wipro — Left Wipro in 2009, but my Service Period/Annexure K not transferred by Wipro

I worked in Wipro Technologies from July 1991 to Apr 2009. My EPF amount got transferred to my new/current employer in August 2009. However it seems Wipro missed to send the Annexure K and probably EPS. Hence my Wipro service period is not visible in my UAN account. I have been repeatedly writing to alumnipf.[protected]@wipro.com since 22-Feb-2023 and later to one Mr.Sharanappa but of no avail. The deadline for submitting Joint Option for Higher Pension in EPF website is 3-May-2023. Since my service period is missing UAN I would loose that service period if Wipro does not take immediate action
