On the 22/02/2022 I created I shipment parcel. I dropped off the parcel to the Dropbox at Southern wood Pick n Pay in Mthatha. When I track my parcel, it always give me the error message stating that my tracking number is invalid. I've been trying to communicate with Aramex via what's app but I don't get any positive feedback. Kindly assist me.
