No delivery and no customer care

I ordered spare parts for a critical repair job, they were meant to be delivered on Monday 05/10/2020. To play safe we decided to do the job on Tuesday, as it required different people from different companies so organizing everyone to be there was tricky. On Monday morning I checked their tracking page and saw that my parcel had been loaded to be delivered that morning. I contacted the client to let him know everything was on track. Tuesday morning I get to the office to find nothing had been delivered. I traced the parcel to see that at 23:30 they had posted that the parcel could not be delivered. I tried to phone the CT branch, what a waste of time, after 30minutes of being "put through to customer services" they just hung up the phone. I called again and asked to speak to the manager who also did not answer their phone, (great leadership NOT) I finally phoned the JHB branch (who had collected the parcel) and asked them to follow up. They told me the parcel would be delivered by 12:00. I explained that this was no good due to the situation and also demanded that they have the CT branch contact me to explain why they did not deliver on Monday as the parcel was on the van and their were people at our office all day. Needless to say they could not be bothered to contact me. I am left with egg on my face trying to explain to my clients why I wasted their time, and fastway just goes on. DO NOT USE THESE PEOPLE. They are ***********, do not care about their clients, totally unprofessional and will give you nothing but a bad reputation and head aches.
