Vodacom's useless ***** department

During July 2017, a ********** phone was added to my account. A debit order of R499 was presented to my bank. A docket was opened and a SAPS Case number was sent to Vodacom, together with all documents in order for them to solve the problem. It has now been 10 months, and still the debit order is going off against my account. I have spoken to 43 people from various branches, including Vodacom's ***** dept. and NO ONE CAN HELP ME, They have taken close to R5000 from my account , and no one thinks it's that important. I am now at my wits end with Vodacom.
