How to change mobile number for PF - lost my old mobile number

Hello professionals,
This is Asha working as an HR Trainee. I lost my old mobile number, which was linked to my PF account.
I forget my password, too. Someone helped me log into my PF account.
I tried so many ways to log in.
I am getting errors like" Aadhaar, name, DOB mismatched ".

Can't you change the telephone number through employer portal? If possible, then after changing the mobile number you may use the forgot password field and log in to the member portal and then correct the date of birth etc according to adhar.
