Unsatisfactory service from UPS South Africa

My name is Kurt Marais from Durban and once again UPS has done me wrong. I have been waiting for my package to be released from from customs at OR Tambo International for a week and I am super exhausted of calling them to follow up and still there seems to be communication issues internally. As far as I am concerned the all supervisors should be fired as they fail dismally in responding to customer service related queries when I am sure they are fully connected and posting on social media platforms in their personal capacity. UPS needs to reconsolidate who they hire as their staff as the current staff/representatives are not representing them to the high customer standards which they are known for. SHAME ON YOU UPS FOR HIRING PEOPLE INADEQUATE FOR THEIR JOBS!!!
