Pennsylvania state income tax refund

I filed my 2022 federal & Pennsylvania state income taxes on 23 March 2023.  Got my federal income tax refund just fine.  But still waiting on my $370 I am to receive back from the state of Pennsylvania.  When I go to the Pennsylvania income tax web site & type in my info, I get the reply that they got my 2022 PA state income tax file & it will take 12 - 16 weeks to process.  Well, it is now 16 weeks, but no refund yet.  How much longer should I wait before scheduling a call with them?
