Contact number [protected]; email id: [protected]@gmail.com

It's been more than a year that I have requested to update the contact number /email address for the Unit -H12307 Alberia.
Recently one of the executive requested to write a fresh email with a Pan card, I have done that as well(10-Feb-21), Its been a week of sending a fresh email to Supertech CRM id. I have got any response in spite of sending multiple reminders the update is still pending. Its been 2 weeks already and haven't got any response
No one is picking the customer care number !
