UPS SCS is a *****

My cousin who works and stays in China bought some items for our family and used UPS to courier them, first of when the parcel arrived in SA it was stopped by CBCU and UPS never bothered to tell me, I then called UPS SCS numerous times to locate my parcel on *** which is their call centre number which they never answer, we called for days with no answer their phone just rings and rings so eventually we drove all the way from Paulshof to Kempton park to their offices only to find everyone just chilling and their phones ringing no stop , UPS call centre agents never answer their phones especially on a Monday or Friday and when they do they are either chewing or laughing , one actually hung up the phone in my ear when I confronted him about his lack of professionalism. When we got there no one was willing to help until we demanded to see their manager , they then sent me a link so I can make payment for the parcel to be released which I did, instead of my parcel being delivered Khutso Matlou sent me an email telling me customs stopped my parcel and they sent me the list of documents I need to provide for my parcel to be released and since then they have been asking ( CBCU and UPS SCS ) for the same thing differently , it’s been almost 3 months now and nothing , no parcel and no refund which to me tells me they stole my parcel and my money. What ****es me off is UPS is rated number 1 courier company which is a lie , their call centre agents need to be fired because they clearly hate their jobs and give other people who want to work a chance. I have been ****med and I want my money back and that call centre along with their managers exposed!
