giffgaff sometimes ban accounts without warning for 'excessive data usage'..
..this causes outrage as everyone expects the advertised 'unlimited data', quite right too..
but someone could be in the middle of multiple huge downloads, and the chance of them picking up a 'warning' email or text sent from giffgaff is quite slim, so i understand when instead giffgaff just cut it off, BEFORE it 'affects other users'..
my idea is..
just like the Adult Content Lock page that pops up if you try to access over 18's sites, i think giffgaff should implement a 24HR or 12HR pop up page to the person who would normally get their internet cut off..
it could read something like:
we have noticed very high volumes of data being used with this account, as a result, we have suspended / slowed down your data use for 24 HOURS / 12 HOURS (whatever), during which we would appreciate if you could read through our Terms & Conditions regarding data use (insert link)
theat way giffgaff can be reasonably sure the user has received the 'warning'.
..and hopefully avoid having to put in place a Fair Use Policy for those of us that know how to use any amount of data in a way that doesnt affect other users
