Frustrated and disappointed customer

I placed an order with cape union mart on the 17th December for a Christmas gift. I was under the impression that this parcel would be here before Christmas. I have made many attempts to try find out where this parcel is via cape union mart and DPD but have had no feedback. According to DPD online help I was told there is a problem with this parcel Ref number and they can give me know information. The email I sent them today has returned email address incorrect. I am extremely frustrated and upset as I have paid for this item and have nothing to show. Rene Nieuwoudt
