Request for lost product subscription key after reinstalling Windows 10

Hi there, I have purchased the F Secure Internet Security for 3 years on 17 November 2018.

However, the seller helped me  installed it and I do not receive any F Secure pack.

Due to some issue that I could not boot into the window hence I format and reinstall the window and lost the F Secure.

May I request to get it back the production key? Those below are the only information that I have.

Location: Malaysia, U Note Sdn Bhd

Invoice No.: XXXXX

Date: XXXXXXXXXXXX

Item: XXXXXXXXXXXX

I can provide the pictures of the invoice also if required.

Thank you.
