No right to debit funds

Multichoice I am utterly disgusted that after over 3 years of not having a contract with you, you have decided to debit R949.00 from my bank account. Upon calling I was advised that your system miraculously reopened my account and due to you still having my bank account details listed on debit order the money was deducted from my account. I was told it would be refunded within 3 business days whereafter my bank account details would be manually deleted. Over a week later and still no refund. Furthermore I called again to be left on hold for over 5 min (total call length almost 15 min). What kind of service is this? And what gives you the right to deduct any money from my account? I do not owe you anything because you are not providing me with a service. How many other people is this happening to? On top of this I received a statement from yourselves stating that on 18 April a payment of R442.80 was made on my account. Is this another amount you will be deducting from my account without my consent? Please sort out your system and give me my money back.
