Address mistake in Online Passport Application Form for Passport Renewal

[helppassport]

Hi

I am renewing passport through CKGS. I made a mistake in Online Passport Application Form. I gave the same address in Address to printed on passport and Other address. I finished the Online Passport Application form and came back to CKGS website and have completed the CKGS application. Made the payment also. I have not yet shipped my documents. What do I do now ? Will they allow me to re do the Passport Application Form alone and link the new Webfile number to existing CKGS application or would I have to repeat the whole process again ? Will they refund the fee if I have to do a new CKGS application ?

Please help.

Thanks
