I once had a problem with Vodafone. I tried calling customer support but, to the surprise of absolutely nobody, the automated answering machine got me exactly nowhere. It also refused to connect me to an actual human being. So I went to my nearest Vodafone store. They said they aren't allowed to do anything except create a support ticket in my name. I said yes please do that. They said okay, someone will call you soon.

Someone did call me very soon. The lady said she was calling from Vodafone customer support, is this Herrvogel? I said yes this is he. She hung up immediately. The end.
