Parcel stuck and no contact made

I honestly cannot find the words to truely express the amount of disappointment I have. I have been waiting for an invoice email from dhl for almost 10 days now. I have made contact with them successfuly 5 times and majority of the time they did not answer my calls despite even waiting on the line for 10 minutes.<br> <br> I have sent inquiries on their website and have not received a single response. In the 5 times I have made successful contact I asked them to email me the invoice yet till this day I have not received a single email. despite me going to their offices in Cape Town and giving them 2 different email addresses from 2 different providers, I don't know why I have not received a single email.<br> <br> I feel dhl has no respect for the fact that we pay a small fortune to use their services and the fact that we use dhl when we need something sent urgently. What is the point of using dhl if your package will take 20 days to reach you? It makes more sense to use a slower and cheaper courier service.<br> <br> Waybill No: WA***
