Microsoft points redeem does not work and customer support link is not working either

bought it with my console back in the day, never used it unvrapped it now... I had better things to do then play but now lockdown made me dig up some old stuff

Since Microsoft points were discontinued in 2013, remaining points cards were made to expire within a couple of years of that. If they won't enter now then there's no way to make them work.

Found this:

If you try to redeem a code for Microsoft Points (that fake currency before the switch to real currency) on the Xbox One, Microsoft Store app or the Xbox.com website,
you will get a "Check the instructions that came with your code. You might need to redeem it on a different web page." and "Xbox. Please redeem this code on your console."

The only way to redeem your Microsoft Points code is on an Xbox 360. The "console" in the above statement is referring to the Xbox 360, not the Xbox One. The Xbox 360 Dashboard is the only software left that
knows what Microsoft Points are. Once redeemed, the points will convert to its Estimated Retail Price and deposit to your Microsoft Account and will expire in a year.

When everything outside the Xbox 360 was overhauled to accommodate the Xbox One and Windows 10, Microsoft appeared to have removed most of the Xbox 360 backend from them (which is why you can't manage Xbox
360 downloads or see all your Xbox 360 purchases from Xbox.com anymore).

yes i did try that, response:

Check the instructions that came with your code. You might need to redeem it on a different web page.

Check the instructions that came with your code. You might need to redeem it on a different web page.

Have you tried it from your Microsoft account online?

Otherwise, where did you get the points from and when?
