I have a question for tax relief especially for books and laptop, do we have to buy these items in Malaysia what if we bought them overseas and we can show proof for these purchases.

I saw a few unifi bills out there where internet, voice and hypptv are itemised. How should one proceed if his/her unifi bill just shows "Residential High Speed Internet". My subscription is VIP10. I also know you can only claim relief under the internet portion of unifi. Any advise?
