Orders not being updated / Lack of Customer Service

ZANDO - I am getting pretty irritated now. I have numerous orders that have been delivered more than 14 days ago - however the status have not been changed to delivered, therefor I CANNOT SELECT RETURNS ON THE ITEMS. The orders that have changed status - happened so late that it does not give me the option to create a return anymore as it was delivered more than 14 days ago - it has now been 30 days, but only now has the status changed from processing to delivered. MY LAST ORDER WAS CHARGED AND PROCESSED TWICE, AND DELIVERED TWICE - this also still shows that it is being processed. I have sent email after email after email. I am now holding for the call centre for longer than 10 minutes already. I have spend thousands or Rands on your site - however I cannot return the faulty items or items that does not suit me. MAKE A PLAN - THIS IS PATHETIC. The other online stores shows that my items have been delivered 5 minutes after the driver leaves. Please contact me asap - as not one of my emails have been answered.
