Do not use the "dash" service!!

I have used SkyNet via Droppa for a number of deliveries, and overall I am super impressed. I can highly recommend it. However, recently I saw a new "DASH" service, claiming a 3-hour delivery within Gauteng. I thought I could get a client their package earlier; win-win. I ordered it before 12:00. By 16:00, no one had arrived to collect the package, so I phoned Droppa to postpone until the next day. I ordered another dash service for another package, this time before 08:00, hoping to have that delivered by 11:00 or so, well in time for the original to be delivered. If I had booked a normal courier like I normally do, the original package would have been delivered in all likelihood before 11:00. I told Droppa that the first package needed to be delivered by 13:00, which should be reasonable, given that it's 25 hours after booking it - far more than the 3 hours claimed. I had to eventually cancel that delivery because no one had arrived, and there was no way they would make it to the delivery on time. By 13:30, still no one has arrived for the second package. Besides the inconvenience to the recipients, and my unhappiness with this service, I am told I now have to pay 30% for the cancellation fee.
