ESIC deduction on above the upper limit of ESIC INR 21,000?

If salary has been revised w.e.f. from sept 2017 which is above the upper limit of ESIC INR 21,000/- and arrear was given in November 2017 salary but the company has already deducted ESIC contribution from Sept 2017 to Nov 2017. Do we have to continue to deduct ESIC amount? Can we stop deducting and refund from Sept 2017 onwards?
Please help me.

Dear Arti,
As the salary is revised in the month of November,2017 and you have already paid contribution till November,2017 you need to keep on paying ESIC contribution till March,2017. You can stop contribution for the said employee only wef April,2017.

Dear Mr. Kamble,
Thank you so much for your revert.
