Plus Zone with the number ***

<p>Just now i have checked my bank statement and found that R 89.99 was debited on my bank account without my knowledge. who are these people (Plus Zone with the number ********** 334)? i tried calling them and this lady picked up the phone and did not even give me the chance to explain my story and just hung up. it may sound like a little money but how did they get my permission to debit my account though?</p>
