unresolved- unauthorised debits

Hi .as from the last incident that happend last week wednesday 24/06/2015 I received no joy but excuses from Nokuthula regarding my UNAUTHORISED debit. She admits fault is on netstar side, how am I liable for payment in June 2015 when I requested cancellation in October 2014? Its not my fault if their systems updated late,how can I be billed for 4 months invoice instead of being asked for payment from the 1st month if I was on the system? Tottally dissapointed with this service provider. Netstar had no permission to debit my account without my consent. Its not fair to debit money from peoples accounts without their permission. I would like for my refund as I have nothing to do with netstar from 2014. If this issue is not resolved within friday I have no choice but to seek legal advise from my attorney for this issue,I was told I would be contacted last week wednesday but to no avail its now tuesday and I did not get the answer I was told that I would revceive last week at 10am. I did ask nokuthula to tell her supervisor to call me but no one had called me.
