HDFC Bank — Premium isn't deducted as per illustration

I've a term insurance with HDFC life. As per my illustration, 2nd year onwards my monthly premium is 2643/- including GST.
But now company is saying that there is a printing mistake in illustartion and your monthly premium should be 3119/- including GST.

I've accepted the policy on details( i.e. premium and sum insured) which are mentioned in illustration but now HDFC life isn't considering my illustration.

Policy Number: 23696587

Please let me know if you require any further information.
