I signed a mortgage loan with cimb 2 years ago to finance an undercon property, for the last 2 years developer never requested money from bank because it was 70% loan margin.

developer recently requested loan disbursement after 2b stage but got rejected by CIMB, reason is because cimb never received mrta acceptance letter from insurance company.

cimb checked came back telling me that the mrta quotation has expired because developer never request money after 2 years, now they are asking me to redo another quotation with additional premium.

if I don't proceed developer will charge me penalty, then I might need to go through a long legal process asking cimb to bear the cost. Otherwise I just top up additional 2k to proceed with the mrta and close this case.

clearly this is cimb fault, I've signed the loan offer letter with them together with the mrta amount stated clearly, what should I do?

thanks
