Very Bad Service

I ordered an LTE-A package from Afrihost which is meant to be delivered by RAM couriers. On Monday I received a message that my device would be delivered on Tuesday. I immediately phoned the Afrihost delivery consultant and informed him I would not be at the Office on Tuesday to receive my delivery and asked for them to reschedule the delivery for Wednesday. On Tuesday the driver phoned when he arrived at my office and I had to inform him that I wasn't available and requested that they deliver on Wednesday. On Wednesday I received a message that my package would be delivered between 9am and 5pm, I was at the office from 07:30 until 17:40 and no courier arrived at the office. I phoned RAM customer care at 17:09 asking if my package was still on route, the consultant said that it was still on route and that they would get the driver to phone me and let me know how far he was and I never received any calls and had no other choice, but to leave at 17:40 as I could not spend the entire evening at the office. This was then marked on the RAM system as an unsuccessful delivery when in fact no delivery was made. On Thursday I phoned customer care again at 08:26 in the morning to find out about my delivery and inform them that I would not be available as I travel to Johannesburg on a Tuesday and a Thursday and won't be able to receive a delivery and can they please reschedule for Friday the 8th, which they said they would do. This was also marked as an unsuccessful delivery on the RAM system and according to my work colleagues no courier arrived to deliver a package, which again is a non-delivery which was marked as unsuccessful on the system. Today I will not receive my package as they need to get authorization from digital planet for a 4th delivery, when in fact this would of only been my second delivery as I only had one unsuccessful delivery and two non-deliveries. No one will let me speak to a supervisor and even though the consultant I spoke to today did see on the system that I mentioned not to deliver on Tuesday and Thursday I am sitting without my package and now not sure when or if I will ever get it. What is the point of a customer care line if you cannot tell them when you will be available to receive your delivery, all the information gets logged on a system and nothing is done with it which also makes the system obsolete and useless.
