Hi, Have you applied for Form-19 earlier or along with Form 10-C? Is your Form 19 (PF) amount settled? If you have not applied for Form 19, then automatically Form 10-C will get rejected. But, if your Form 19 is settled, then they may process Form 10-C. However, if you are eligible for Form 10-D, the PF department will reject your claim for 10-C, provided your age is equal to or more than 58 years.
If your age is less than 58 years, you are not eligible to claim for 10-D. You have to apply for another scheme certificate for your last service.
As suggested by Mr. Alok Singh, it is better to visit your regional/sub-regional PF office immediately.
