Do businesses actually choose to use them?

Traumatic experience. Terrible communication. Links do not open. Whatsapp does not exist. I have been trying to keep track of delivery for weeks as I am not always at the delivery address. I wanted to ask them to please give to a colleague, but there was no way to do that. Out of the blue, I got a whatsapp from a driver to say that parcel would be delivered. TWO MINUTES later he arrived and because I was not there, the parcel has been returned (I hope. I have no idea what happens now or if I will ever get a refund) I called him back 30 minutes after he had arrived and left, and he refused to deliver even though he would have been close by. Extremely rude and aggressive delivery person. He did not listen at all... Just berated me for a full 5 minutes. I am very concerned he now knows where I work. And still no parcel. Buffalo couriers - your predelivery communication needs a lot of work. And your unprofessional drivers are a reflection of your brand.
