RAM not delivering the service the promised

After I spoke to several people, I chose RAM to courier my parcel. Not even the cheapest one. I picked the next day delivery option which cost a little more than usual, especially if you compare it to their competitors. In the morning (of the day of delivery) I spoke to the call center via live chat, David, to ask a estimated time of arrival and was told that my package is not in Cape Town yet but will be there the next day. SO I paid MORE for a service which RAM failed to deliver to me.... this seems a little like false advertising. I needed the package to be here the next day and therefore chose RAM Couriers as they seemed dependable, I was wrong and its a inconvenience . I see now on Hello Peter that this is not the first time this has happened. Why am I paying for a service I'm not getting? This is terrible service and I will go with a different courier next time as it will safe me time and money.
