CIO address mentioned in application kit.
if he sent on wrong address I doubt CIO not recieved his application.
Look previous post of the same OP I mentioned same thing.
Who recieved your application at CIO any tracking details you have?
if CIO do not found record means it's clear that they don't recieved your application.
Ask courrier company regarding this (if you sent by courrier). if you sent by post then apply another application if CAP is there, about bank draft you sent for fees, you can cancell it from bank.
you can not do anything if CIO not recieved your application and if application delivered at wrong place by post.
OMM
Which courier service did you use? FedEX/DHL or any other? If it is FedEX/DHL, you can even tell them who received it from their office and at what time. You just need to use your tracking number and courier's website to know this information.
Similar services are available with most of the International Courier Services.
I was also wondering if you had mistakenly mailed it by regular mail in their courier address, then also this problem can happen. Address for regular mail and courier are different, just in case.
Thanks and regards.
