For WES, you are right. It may take 10-15 days. IDP or British does not issue IELTS result easily. If they agree, it it may take 3-4 weeks, plus 6 days of courier time to CIC.
kollins said:WES ECA report can be ordered and delivered within one week.Just go to their website,login to your account and order for another copy to be delivered to you via international courier.
For IELTS,you need to meet British council or idp(whoever conducted it for you in your area) and request for another copy.They will tell you what to be done.
Cheers.
