My PG college lost all my educational original certificates.

Hello Sir, I submitted all my original certificates (SSC, Intermediate, Degree, Income Certificate & Caste Certificate) to my college at the time of joining my PG course. Now it's been 4 years and I couldn't complete my PG course due to some obligations and I am willing to discontinue my PG course. Hence I requested my college to release my certificates and they asked me to clear the pending fees. I told them I'll pay the fees once I get to see my certificates but they keep on saying to pay the fees first then the certificates. Later I came to know that my certificates were midplaced/lost. I had attended few interviews recently and holding offer letters. I am about to get a job but I can't get it now unless I provide the certificates. The college is not ready to do anything about it, they are not willing to give any letter stating the loss of certificates for filing the FIR. I don't know what to do, where to go, whom to ask and who can help. I am under mental distress I have to get a job for myself at the earliest which doesn't seem happening any sooner or later. Please advise me or guide me through to get my certificates as I can't even bear all the expenses to get the certificates. Thanks in advance.
