Nonsensical service

So they decided to call me and telling me that they’re downstairs to deliver my parcel. Who the hell think they are. We have businesses to run so you can’t just show up and expect me to be available. When I spoke to some lady on their 010 number she was very rude and even hung up. You can’t expect me to stay indoors the whole day and wait for delivery as if I have nothing to do. They need to be professional those Guys especially the call center people. Call us and give us an estimated arrival time . You can’t expect us to wait for you and then be rude when we tell you that you can’t do that. This is nonsense
