Sorry to hear. Best thing to do is send is a message using our support form at https://meh.com/support. Be sure to select the correct order number. This makes it easy for our team to look up shipment details so they can get back to you quicker (due to high order volume our customer support team is working through a backlog of cases).
If you’ve already sent a message through the support form you can keep your eyes open for an email response and also monitor https://meh.com/support/tickets for a reply.
