Not receiving an item

Description

Hey everyone, I made an agreement over Facebook to purchase 2 tickets for an upcoming concert on Saturday. All seemed well and good and the deal was planned out, so I sent money via PayPal and have still not received the tickets. I originally contacted them and asked for a refund and they said they would and now I have tried to re-contact them, but my messages are coming up as non received and I’m left without tickets and my money. Can anyone help? Thankyou!
