Do you have the link please?
I called the phone number, they told me they’d call me again, They did, but I kept getting into other customers’ lines so I told them this was a scam. What a weird phone call lol!
(I can't really explain it better than this lol)
The way to tap into the other customers’ phone calls is by pressing 1 btw!
NVM, the extension doesn’t work anymore. 
Voicemail
