Magyar Posta delivery

I ordered from Britain one medicine. It has arrived to Hungary one of Magyar Posta warehouses. I made payment as they requested for custom clearance they carried. And now as was written in instructions, after I have made payment, they will deliver to my address. The problem is that I made payment in 28th of April. It is 3rd of May and they haven’t made delivery yet. What should I do? Should I call them or continue waiting?
