Delivery promises not forfilled

I ordered the Rain LTE-A from Axxess more that two months ago and when I inquired about it I was told that Digital Planet would be doing the delivery.

Eventually a consultant form Digital Planet called me on Thursday (the 23rd November 2017) to arrange/confirm delivery. I shared with him that it is part of my job to travel so the date agreed would have to be the date they deliver as I am not home during the day. He then assured me that they would deliver on Monday the 27th November at one of my work site (that I shared with them). He also said that the driver would call me in the morning to confirm the time.

On the 27th at 09h30 I called the number that I received the call from only to be told that it was not dispatched and would be delivered on the 29th. When I shared with the agent that this was not the agreement she became rude and when I asked about speaking to someone that can listen to the recording and confirm why I was promised the 27th only to change the date without my consent she then put me on hold for more than 3 minutes only to tell me that the managers are in a meeting and would get back to me.

6 hours later still no feedback and no delivery. I ask myself why do companies trust Digital Planet if all they can deliver is Frustration.
