Gave them notice I was finished with my unit which will mean I will have used just one week out of my pre-paid month. They will refund my unused weeks... but as per their "terms & conditions" they will take up to 21 days to do it !! So I pay them upfront and when they owe me money they get three whole weeks to send me what I'm owed. Sharp practice and pretty nasty customer service. I really wouldn't recommend Magenta at all. For same price I could have had Yellow who provide 24/7 secure access rather than just daytime and refunded unused weeks right away when I used them. Magenta, best avoided.
