Pathetic service. 14 April I phoned to ask to change the payment date and cellphone number. The lady said that she may not do it and I must email Vox. 17 April I emailed Vox to ask for the changes. I received a reply saying that they have received my email. 19 April I emailed again to ask for the changes to a different email address plus the previous one. Received an email saying that they have received my email and I must use the app. Tried the app, but it isn't working. Try going online, but it doesn't log in. 20 April I emailed again asking for the changes and said that the app or website is not working when I want to log in. I am still waiting. This is the worst customer service I ever received.
