When I messaged the seller this was the reply

I am sorry for your long waiting. With free shipping.
Generally speaking, delivery time of regular mail may take up to 3-7 weeks to your country due to strict Custom Inspection. dont worry,it is on the way. could you please wait more days

Today is 18th March 2017 and I still haven't received my order.
Should I open dispute or not?
