Bad experience at Taipei liason office

My appointment to collect Visas from the Taipei liason office in Hatfield Pretoria was at 14:30. I was refused parking by the Security officers when I arrived at 14:20. Security told me to park my car outside and acome back at 14:29 if my appointment is 14:30. I explained to the Security offocer that it is impossible to arrive one minute before an appointment due to current loadshedding and traffic constraints but he told me to go and park outside in the street. He was rude and refused to give me his name. I hope Taipei liason office management realise that your experience when visiting their office starts with Security at their entrance. My experience was that Security is rude, spiteful and not helpfull at all.
