You have mentioned that the PF authorities informed you that they had sent a cheque to your bank, but you did not receive the money. In this case, I assume that the name in your EPF account and the bank account is different. That is why the amount was not credited to your account and was sent back to EPFO.
Steps to Resolve EPF Cheque Issue
Therefore, it is advised to submit an RTI to the concerned EPF Office with the following queries:
1. What is the current status of my EPF Account No. ___________?
2. Has the account been settled? If yes, when was it settled?
3. Under whose name and to which bank was the settlement cheque sent?
4. Was the cheque that was sent credited to the Payee's account? If yes, what was the account number?
5. If the account was not settled, what is the current balance in my account?
The response to this RTI will clarify all your doubts.
Before submitting this RTI, please visit EPFO (Govt. of India) at
http://www.epfindia.com/ and check your EPF account balance. If you have received an SMS regarding your balance, it indicates that your EPF account has not been settled. If there is an error such as an invalid name or account number, it means there is a mismatch in your name in the EPF account. You can also verify your name in your EPF Slip if you have one.
I hope this information is helpful to you. Cheers.
