It could just be me and my crappy phone, but this happens to me occasionally and it’s really annoying. Basically as soon as I’m done listening to my voicemail I press 7 to delete it, but every so often it doesn’t seem to register on it that I actually pressed 7, which makes the voicemail system continue with its shpiel. No matter how many times I press 7 at that point there’s no way it’s going to delete the message without me hanging up and re-calling the voicemail upon which I’ll have to listen to the message yet again and press 7 to delete it. Maybe it’s my crappy phone, maybe it’s their stupid system, I don’t know.
