Paramount Group — late fee of registry

Address:

Oxford Square Supertech Exo village -3, 201318

Registry fee for flat l-805 paramount on dated 14feb 2019 was submitted but builder ask to submit late fee from 11th feb 2019. They did not have issued any latter for intimation of registry. Now paramount is telling that registry can be done after late fee inclusive period from 14th feb 2019 onwards also at which fee was submitted. Then why i should pay late fee for the period after 14feb 2019. Please ask builder to do my registry as per rule as delay is not from my side.
