Rude and dishonest service

A parcel was sent to me on 15/05/2023, on 19/05 I received a call from the sender saying Courier Guy cannot get hold of me. I was in training and could not take any calls. Apparently there was no one home so they could not deliver. On Monday she called me again, I provided her with an alternative number as I work on a mine, and the signal at work is bad. Today saw a missed call from a landline, and called back, they mentioned who it probably was calling, and said they will call back. In the meanwhile, the sender forwarded a message to me from Courier Guy saying they cannot get hold of me and people at the address say they don't know me. This to me is confirmation of the delivery person taking short-cuts again, or are at the wrong address, I tried calling the office again (19 times) with no answer on 2 different numbers. In the meantime I missed a call and called back, it was a lady saying she's at home wanting to deliver. I explained to her that I feel this service was terrible. I tried explaining that I have previous experience where drivers claim they could not get hold of me, while I was busy outside and there was no-one, and that too was not the first time I experienced this from Courier Guy. Needless to say, the conversation got heated, and she shouted at me saying they cannot wait at my house the whole day for delivery. I said if they bothered to answer their phones an arrangement could be made, and she reconned it is irrelevant that they don't answer - so clearly if they cannot get hold of me, then I am threatened with paying penalties and my parcel will be returned, but if they don't answer to try and resolve the issue, it's irrelevant. I don't expect special treatment, I just feel this is not on. She claims the contact number has been changed numerous times, and the whole issue is my fault. I will rather in future use another company seeing to it that I have caused so many issued for them to deliver and they obviously do not have the capacity to deal with problems that their own driver's cause.
