Who To Contact If PF Withdrawal Amount Doesn't Match?

I worked in an MNC for 3 years .After my resignation, i applied for my PF withdrawal.
Then i got PF balance details as
EE amount : 30273
ER Amount : 14783
But after withdrawal procedure is done from my end, they transferred amount of 28,570 to my account.
I don't know whom i need to contact EPFO or Company ?
Please guide me.
