Hi I applied for pip 22nd August only had a text that’s it . But today a brown envelope has came though my door but nothing inside it was as if hadn’t been sealed properly. The return address is PO BOX 585Belfast . Could it have anything to do with my claim would they just turn up at my door or something I’m freaking out . Why would I get an empty envelope. Can anyone help my anxiety is through the roof 🥲😩 thank you
