Courier company phone numbers on google not working

Google is quick to label websites, especially those of link sellers as spam, however many of the details in google results are not accurate
For example a courier company phone numbers listed in google search are not working
The user is wasting a lot of time contacting the courier company on phone , there is no reply at all or the number is invalid message obtained.
Google should mention when the details were last updated, so that people do not waste their time call up numbers which do not exist
