Digital Advertising Alliance isn’t allowing me…

this is the screenshot of the result I keep getting after trying over 10 times to opt out of the 124 participating companies’ ads of Google. Zero successful results for me; as for my friend, he was able to opt out of only 7 companies out of the 134. This option is btw from Google’s ad settings from myaccount.

What can I do? Should I just give up on trying to opt of the damn ads? Thanks in advance.
