AFTER 100'S OF EMAILS AND LOADS OF FRUSTRATING PHONE CALLS I WAS TOLD THAT THIS WASP SERVICE HAS BEEN CANCELLED. BUT YET AGAIN I HAVE BEEN BILLED THE \CONTENT SERVICE"CHARGE AGAIN THIS MONTH. ***...WHO CAN HELP ME??? THESE GUYS ARE *****ING FROM ME AND NOTHING I DO IS HELPING ME... I CANNOT CANCEL MY DEBIT ORDER BECAUSE THEN MY PHONE WILL BE SWITCHED OFF BECAUSE VODACOM ARE THE BILLING COMPANY FOR THESE GUYS RUNNING THIS WASP SERVICE??? I REALLY DON'T KNOW WHAT TO DO ANYMORE.... IT IS TOTALLY UNACCEPTABLE THAT JUST ANYBODY CAN HELP THEMSELVES TO YOUR CASH EACH MONTH"
