Delivery first: the moment you pay, we send the download link and access details to your email within a minute — even on holidays — and the files install on unlimited computers; contact support if 2 hours pass with nothing. For refunds, the terms are explicit: take the corresponding ITILSC-OSA日本語 exam within 60 days of purchase, and if you fail, submit a scanned enrollment slip plus the official Score Report PDF within 2 days of the exam for a full refund, processed within 7 days. Excluded: exams taken within 3 days of purchase, name mismatches between candidate and payer, and free or expired products. The alternative to a refund: two equal-value exam products free, with your original updates intact.
