ICICI Prudential Life Insurance — No update on PF withdrawal

I'm Reshnaja from Chennai, Tamilnadu. I'm a former employee of ICICI prudential dated Oct 2018 to Jan 2020. My employee code is 5063739. I applied for the pf withdrawal on Jan 15, 2022 through speed post to ipru pf department office Mumbai, and also received a message that the speed post has been delivered. It's been a week that I have been waiting for the pf amount to get credited to my account. I get no updates from the company, I'm very helpless and not able to track the status as well. Please find me a solution for my PF withdrawal process.
