Received call from local GST office , should I worry?

person introduced himself from local Gst office and asked me why haven't I filed my monthly GST 3B told him I have opted for QRMP for this quarter, he enquired whether I have any accountant/lawyer who files for me, told him that I myself learned from YT and files regularly. Is this routine call or should I worry total call duration was approx 3 min.
