Back office staff are on permanent leave

Today marks 3 weeks that we have been fighting for a parcel from UPS . The parcel was invoiced to the wrong company which meant that we could not pay the invoice and subsequently they could not release the order . In an attempt to correct the invoice details we have been phoning the customer call center NON STOP for 3 weeks , we have sent several emails , all with no answer , no response or simply to be "put through " to another department who does not answer their phones . We have concluded that other than reception , there is NO ONE in UPS back office actually attending work. Yesterday my colleague drove from Pretoria to Kempton Park offices to try and resolve the matter , not only was she bluntly ignored by our "correspondant" Henk ( who eventually returned to his office and did not return to assist her) but when escalated to the Country Operations Manager , it was made clear that customs documents we had been sent were FALSIFIED . We have tried all avenues to escalate the matter . All are a dead end . UPS , Ultimate Poor Service .
