2nd complaint! No delivery - Ref ***

On Wednesday 23 Sep I called the CPT airport depot, spoke to Shakierah who quoted me for a overnight express delivery to Nigel in Johannesburg. She assured me my delivery will be delivered Friday 25 Sep by 11am. I delivered my package to the CPT airport based on this information on 23 Sep, quotation was done by Chrystal Reinhardt, who I questioned again and asked check the area, will this package be delivered by Friday, she assured me its a central area and will definately be delivered on Friday. Today I check online to track the package, no progress...I called the call centre at about 2pm, they assure me again the package will definately be delivered today. At 16:30 today nothing is delivered and I call the call centre again, all they could say was its outlying and they can't give me any information, I should call the jhb branch, no answer! This is the second time this has happened and I am furious! Unacceptable service and staff need to be trained on which areas are central or outlying! I specifically paid for an overnight express delivery, confirmed with three different staff members that my package would be delivered on time!!! If not delivered in 24 hours, I want a refund!
