Worst service ever

I had to have documents couriered from Namibia to South Africa, the package was booked on the 18/10/2018 and to date I have not received the package. When phoning both the Namibia and Johannesburg branch I was constantly given the run around and promised each time it will be delivered the next day. Each day I had to phone to do a follow up as no one gets back to you. Eventually the package arrived in South Africa and I was promised the next day I would get it at 09h30 - 09h30 came and and went and when I again phoned the Johannesburg branch I was told it will only arrive at 12h00. 12h00 has come and gone and again I had to phone them and was told it should arrive before 14h00. They do not know what to say as they only have one driver. When you make a complaint they say that it is the Namibian office's fault that it has not arrived. I am truly appalled at the lack of service or regard for me the customer. Considering that it has taken almost 2 weeks to be delivered one would think they would expedite the parcel to be delivered as soon as possible. This is not the case at it seems they are not worried about their customers. When I wanted to phone their landline number I was told that does not work and their email addresses that appear online are no longer valid. This is honestly the worst service that I have ever received from a courier company that I have worked with and I will not use them again.
