No Response received

Good day<br> <br> I have tried on so many occasions to contact this company by email and still no response received.<br> Why have email contact details on your website if you do not respond to emails?<br> I am trying to open an express account for my online business and nobody seems to be getting back to me.<br> I really really need urgent assistance as this is holding up my web developer and we cannot go live without the DHL API.<br> <br> Thanks<br> <br> Tercia
