UPS South Africa - Useless

I have had the worst experience ever with UPS South Africa. A package was shipped from Italy to our offices on the 8th of October. The package arrived at South African customs on 12 October, since then I have had to phone your call centre 6 times to try and get the package delivered with no feedback or communication from UPS whatsoever to date. We requested the invoice from Thandi Gama on the 16th of October. When the invoice was finally delivered payment was processed and the proof submitted as per usual. Several days later we still had not received any feedback. When I then phoned your customer services centre again to try and find out that was going on, I was told there was some glitch where the proof of payment was present on the system but not provided by UPS to Customs. The package was immediately released by Customs to UPS. Still no delivery! I once again called your customer service department who stated that no payment had been received and transferred me to the invoicing department who confirmed that all payments were complete. I was transferred to Bryan who could not understand why the package was now held at COD. I was transferred to the warehouse where I spoke to a man who promptly left me on hold for 30minutes and then dropped the call. Another 30minutes of calls later I was told to collect the package myself as no delivery could be arranged before Monday! This after I had to lead each and every UPS department by their hand to do their work! Worst service our company had ever had with regards to a shipment.
