Worst courier company

I am utterly appalled by the service that I have received from your company. I am a first time user and I only used typo based on the recommendations of people in my network who have used you. I had a document picked up on the Wednesday the 17th of February for delivery the next day to the university of Pretoria. This is an extremely important document. Firstly you send me a tracking number and by 3pm of Thursday the 18th of February it was still stuck on collected. I made numerous calls and your staff have been moving from one person to another with no results. You put me on hold knowing fully well that after 2 minutes your calls drop. Call back and get put through to someone else. I was given an incorrect number for Equestria and I had to call head office again. The number I was given the second time the gentleman I spoke to said he would call me back and he never did. I called again an hour later and spoke to someone by the name of Morne who told me to go back to head office and speak to either Randy or Bevan. I called head office and I was told Randy wasn’t available and they would put me through to Bevan. I was on hold again and then your lines got cut. I called again and I was told Randy was available, I was put through again and after 2 minutes your calls cut again. I called in yet again and I was told Bevan is not at his desk and they took down my details for him to call me back. An hour and a half later nothing and when I called again I was told he has left for the day and put on hold. Is this how you treat your customers? Honestly would you accept this kind of treatment if not then why are you delivering it. I need to know where my document is? Can someone get back to me as a matter of urgency
