So now my lines are can cancelled 1st Of March, but guess what I still get invoiced for March when I RECEIVED NO AIRTIME AND DATA BECAUSE MY LINES WERE CANCELLED total and utter *********** fools please sort this out so that I do not get debited at the end of the month. I have sent numerous emails to try and sort this out nothing has been done.
