how did you receive the notification/?
Sorry about the late. I got this error message when I pull up a browser/search engine. This message will automatically shows up. Seems that they've finally fixed it and I don't see this notification lately regardless if I consume more or less 10gb/day. I'm hoping they have sorted it out.
I was able to redeem my spotify free for 3mons too, glad they have fixed their registration site lol.
