Disgusting service from Sunridge Park Post Office in Port Elizabeth

Disgusting service from Sunridge Park Post Office in Port Elizabeth. I waited months and months for an order to arrive from overseas, after phoning JNB customs they said the parcel was delivered to Sundridge Post Office, after going there they said that they returned the parcel to sender because nobody collected the parcel - yet we never received ANY notifications to collect!!! The company from which we ordered has closed in the meanwhile and thanks to Sunridge PO's incompetence I have now lost R5000. When asking the manager for proof that they returned it to sender (a tracking number or slip for example) he couldn't provide us with ANYTHING and we have to take his word for it. Not even as much as an apology, and he went about systematically gaslighting, taunting, verbally and emotionally abusing us, yet it is 100% their fault that the package was not received. Absolutely pathetic service and gross incompetence by this branch and branch manager.
