Robo call from Amazon saying I needed to speak to them to cancel an order for an iphone due to be delivered tomorrow to a different location. 3rd one I've received from 3 different numbers today. Decided to stay on the line, the call centre worker said "hello", and I instantly (and politely told them I'd received several calls from them today and kindly asked them to remove me from their dialler as I don't care about these calls and they just hung up on me. How rude!!
