Poor,poor service ,very disappointed and im shaking with anger

This is the worst expirience of my life I've ever had , on the 07th Aug 2018 i had arrange for express documents to be sent from DHL germany and i paid 72,90 Euros so i can get them faster . Today I've logged on using my tracking number ********** 273 and to my surprised i was told that the address on the dicument doesn't indicate the suburbia and i immediately called after 8 am this morning to get clarity got through to an agent that told me the documents will leave depo at 12 and i gave them the address and i stressed completely the importance of these documents as they are required urgently for my international travel . The agent told me to call back again to follow up as they are around 11 am and i did just that after 10am and only to be told that the documents are at east gate and won't be possible for me to get them before one as they are being sent to sandton (bryanston to be exact) , i completely freaked out and spoke to the call centre supervisor who then told me the only way is for me to collect in Sandton and i suggested the branch next to Gautrain and we both ended the discussion in agreement that she will organise for bryanston to send them in the branch at sandton at around 12: 00 ish . So on my way to the branch after 12 i made a call to gind out if documents have arrived and only to be told no the documents are at the airport and mind you i had stressed to the supervisor on how absolutely these documents are of agency and i the lady at sandton who was on the phone recommended that i call the call centre again and i did , it was worst service ive ever got in my entire life. Not only i was fortunate to speak to the lady who was handling this issue but she absolutely denied that we agreed on the time and whats worse was the rudeness of some agents that i spoke to who were not willing to find out the supervisor i spoke to after i had been put on hold for 30 min by the supervisor who still now haven't gotten back to me . I am forced to pay 380 to reschedule the appointment which now leaves me we a tighter scheduled for my visa application.

This is uncalled for, am so appealed and disgusted by the fact that I'd pay for service only to be belittled by the staff of this company especially those who are in leadership such as this supervisor who put me on hold and had no decency to call me back with a feedback.
