DHL Terrible service,customer avoidance and call dropping

I’ve been trying to get assistance from DHL in midrand for a parcel set to leave for Zimbabwe..the initial lady was helpful,when I received the waybill most information was spelt incorrectly despite that I had taken time out to spell everything for her,then there was an error that I couldn’t change on my side and I called DHL midrand back,the lady named Pearl referred me to another department where I dealt with an unpleasant employee who refused to understand what help I was asking for,his name was Sechaba,I had to end the call. Did everything myself on my side and wasn’t able to update-I was forced to call back and ask for Pearl,whom I still struggled to reach as though she was avoiding to take my call and the person who answered tried to take me back to Sechaba’s dpt which I refused then they assisted and also noted the multiple spelling errors and typos which I requested to change-as the director of our company would be checking as the parcel is direct. The gentleman who helped sent the link back and I told him that the reason I opted for my personal email was because Pearl had incorrectly spelt the company email,he pretty much refused to change the email saying it doesn’t make a difference-when I insisted as my boss would be terrified at the error-he cut the call-I called again was put on hold once again until I gave up to get assisted for the parcel going to Harare.We’re running a business and it’s appalling to receive this kind of service.
