late and no delivery at all

we posted a few parcels with Aramex over the Christmas period.<br> Parcels were posted on the 22nd and should have reached on the 23rd <br> <br> we have customers still waiting for parcels and today is the 30th. <br> <br> when we call the call centre they keep making excuses. what kind of excuse is \not enough drivers"for a courier company.<br> <br> i demand a refund for all parcels delivered late.<br> <br> once we had to change a cell number for a parcel. i call and arrange to have the number changed but still the parcel gets delayed because the delivery guy did not get the new number"""
