BAD CUSTOMER SERVICE

I made a call regarding my outstanding Wonga account asking about settling my outstanding balance, the lady I spoke to by the name of Zinzi Zama who just hang the call on me. What kind of customer service is this????? All i needed to know was if the Debi check mandate was approved and that how would it affect me should I make a manual payment to settle my account. If i offer to make a payment, why does Nimble Group( Zinzi Zama) hang up the call on me. If there was a technical issue, then she would have assigned someone to call me back. But Nothing!!!!!!!!
