I have called customer services three times with this issue and they can't help. I am trying to set up voicemail. When I dial 222 I get a dead tone. The same goes for holding down 1 or pressing the voicemail icon. Customer services said they'd send me a text TWICE with a number on but I have still received nothing. My handset is an iPhone 5 and I've recently transferred my old number across. Please help!
