Pf Office — regarding the less deposit of employee share by employer

Respected sir,
I am patil arvind govind, my uan is[protected]. I was employee of shri bhogawati shetakari shikshan prasarak mandal, shahunagar, parite.
Employer taking rs.1560/- share from my salary from november 2014 after change in rule. But they paid only rs. 780/- in my pf account.
When i asked about this to institution then they said that they are unable to pay to pf office.
I have already given application about this to pf office on 13th november, 2018 but from pf office also i am not getting any information. Again i met one of the person in pf office on 11th january regarding this. They assured that they will take action and inform me. But till today i am not getting any progress in this regards.
Hope i will get help from your office to get my money back in my account with interest.
Thanking you.
