Suspended my dependant's account

I sent Discovery an email last Monday 1st Feb 2016 regarding my R7200 credit on my name.. Still no response or phone call., Zeenath Subrati (MailRef#***#-)sent me an email in this regard. I received an email from Reuben Nditha to say he will be escalating my credit query refund.Still no response. Today my dependent, Miss Lynne Williams, for whom a continuation form was completed and acknowledged - ***, receives an sms to say her account has been suspended! How can my account be in a R7200 credit and her's be suspended when I'm the no longer a member but paying for Miss Lynne William's account???<br>
