I phoned them up today to disconnect the old number.
10 minutes went by, "a vodafone rep will be with you shortly"
2 minutes later "Vodafone answering service" ANSWERING SERVICE!!!!!
I told her that for the wait and then get an "answer service" I am disconnecting my account (it was the intention of my call, and I was very pleasnt to her.) Never get agro at an innocent CS rep unless they are making screwups.. Rule #1
