Poor customer experience

DHL express charges premium prices for "quick turn around" and even allows the customer to pay for duties and clearance upfront so no additional charges when an international package is delivered to you. There is no contact number , pushing the customer to self service via the website with a waybill number. My delivery was meant to arrive by end of day 16 Feb and the site continues to reflect this yet it did not happen. I have called in no less than 5 times getting pushed from pillar to post without anyone resolving or getting back to me. In my opinion they charge exorbitant rates for very poor service. Their site is not updated and is very frustrating.
