Dhl durban poor service delivery/customer service feedback

Dhl sends me an sms early im the morning reminding me that my shipment is scheduled for delivery today by the end of the day.

Waited all day for shipment, whilst occasionaly tracking progress from april the 12th only to call dhl durban and find out late in the afternoon that my parcel was off loaded from the courier van as my customs clearance fees have not been received. Firstly payment was made om 12 april and my parcel was released from jhb customs to durban for delivery...only for durban to holt my delivery without notifying me, saying payment was not made.(they will not release my parcel from customs jhb without me paying) I waited at my place all day to sign and receive my parcel as per dhl morn sms. When i finally do call i spoke to a lady from the durban branch who informed me she would sort it out, i then had no response after an hour so i decided to call for the second time, where i was rudely cut off the line by a male customer service provider. I then called again and spoke to nthabiseng from dhl customer service who informed me that he would call me back by the end of business...i still have not received any feedback or my parcel.. Absoloute terrible experience
