Terrible service by RAM couriers

I took leave to wait for a parcel that was to be delivered on 5/10/2018. As RAM does not provide a time and this was an important delivery I had to make arrangements to be home. Nobody came and nobody contacted me. I started phoning their customer service at around 16h30 and could get no answer about where the delivery is. I engaged with them on live chat and was informed my parcel will be delivered before 17h00 and I will be contacted when the driver is in the area. Nothing happened and then suddenly my delivery was logged as unsuccessfull on their website. I phoned again and again and was informed that an e-mail will be send to a manager and I will be phoned back. Nothing came of this. I have got cameras on the outside of my property and I have proof that no RAM vehicle even approached my house. Logging this delivery as unsuccessfull is dishonest and the fact that I received no feedback as promised clearly shows their attitude about custumer service. I have also contacted FNB to inform them about this as I do not want RAM to ever deliver anything to me again. This is still unresolved and I still have no answer as to when a delivery will be made. This is my second bad experience with them, they do not take responsibility for this and the delivery problems never lies with them.
