Super slow couriers , No communications , Worst service !

A parcel (2R***)of mine was collected by fastway couriers from Pretoria on the 10th , the parcel is supposed to be delivered to me in Escourt , I received an email from them saying my parcel will be delivered to me in 3 working days and I received a tracker number to track it online . On monday the 14th I tracked it and the response was I should expect delivery this coming wednesday (yesterday) I did not get the parcel , I called their Durban depot and I was told my parcel was received in Pietermaritzburg yesterday so I should call them , I asked my cousin to call them for me the person she spoke to said my parcel was on their desk and they could not locate my area (mind you the parcel has my address ,my area code ,my cellphone number & my email address) so the said they will call me and double check my address and my parcel will only be delivered on Monday as their next deliveries will be done on monday .
