Incomplete Shipment

I have ordered from the online shop 9 days ago (3 June) and still haven't received all the items (even though they were invoiced and marked as shipped). I was told on Monday (8 June) through the online chat that a second package would be shipped, but I have no tracking information and my queries for delivery information are ignored. When can I expect delivery for order ***? I understand that mistakes can slip in now and again (not shipping the correct items), but the manner in which a company solves a problem and communicate is the real indicator of good service. Not impressed at all.
