Yes. You can file RTI application to know the reasons for delay in PF transfer.
The RTI application should be addressed to the designated PIO of the concerned PF office mentioning details relating to the PF transfer. The application must contain details like EPF Account Number, EPF Code, Name and address of Current and previous employer, EPF office holding old account, EPF office holding new account, Transfer application date etc.
As applications relating to PF transfer are filed online on the government portal https://rtionline.gov.in the wait time for getting a response can be expected to be a little less than usual.
