Despite almost exclusivley signing up to this service for the data rollover i have never recieved any. The first two months i had 5 gb left and the 3rd month i had 8gb left but each time i top up it wipes what was left and tells me my rollover is 5mb.
I called up boost only to be told i had used all my data each time and that i am the one who is wrong and not boost.
