After you file

What is the irs referral process? I have filed my taxes jan29th and the beginning of February they selected me for a random review and it’s been over the 60 days they said it would take. And so I called up because they told me if I didn’t hear anything by today to call up and they said nothing was updated so she was gunna put me in for a referral and give up up to another 60 days? Has this happened to someone before? I’m sure it has so what’s next
