Cancelled data before the end of the month

So again Vodacom, you took data before the due date. You promised me that once my contract is cancelled I have until the end of the month to finish my data. I woke up this morning (not yet 1 Nov) and my data was gone. The sam goes for the airtime that I keep loading on another number and without making calls or sending sms, you use my airtime instead of the data package loaded....how come. You guys are *****s. Thank goodness I am going to another service provider tomorrow as all my contracts are now cancelled. Cheers *****s and ******* network!
