I have been selected for one of the organisation and they asked for 10th and 12th marksheet as per their company policy.I submitted the same and got the acknowledge letter saying "we have taken 10 and 12th originals of xxx candidate".Now due to personal reason i cannot join that organisation how can i get the originals.I have not signed on any document of the offer letter. I have signed on the acknowledgement letter of originals marksheet which they have given to me.If i apply for duplicate will there be any problem or else what can i do?
