Bad service delivery - Witbank

I received notice on 29 Jan that my parcel would be delivered that day. 2 minutes later the driver called me to say he was at the door. As we were not at home I asked him to wait 15 minutes & we'd be there. He said he was unable to wait. I asked that he return the next day. I was told he couldn't do that as the parcel would be returned. That, to me, sounds like a lot of *******. How do people get their parcels if they are at work. We eventually agreed that he would send a location pin and we would meet him there. It was 2 blocks from our house - I don't understand why he could not have waited. He had also signed the package using my name & a squiggle that could've been anything (definitely not my signature). I wrote to Buffalo to complain (4 days ago) & was told they would reply within 24 hours. No feedback at all. Is this company so big that they just don't care? If I get the choice I will never use them again. Appalling service
