Late Delivery / No Answer

My package has been unnecessarily delayed in Johannesburg because it arrived on Friday and UPS doesn't work on weekends. I paid a premium rate for express service and yet UPS South Africa has chosen to neglect my package once again. If I had a choice not to choose UPS before making the purchase online, I would have definitely chosen FedEx as they are always reliable and enthusiast. UPS has on the other hand has not answered a single one of my calls when I tried to call their call center today. If you have a choice, I strongly recommend you do not uses this courier company's services. Their poor customer service and lazy delivery service is unacceptable!
