Disgusting Service

<p>I up-graded a cell phone @ Vodacom shop Clearwater Mall in July 2016, I was unhappy with the service I received and also the phone, I spoke to the manager of the store and he agreed to reverse the up-grade which took nearly two months, in the mean time Vodacom charged me with the monthly installment of the phone and a connection fee, I did not pay these amounts but phoned Vodacom and they agreed a credit was due and issued me with a reference number S3-G3H2X-X1BK3, I am now receiving threatening calls and SMS's saying my phone will be blocked unless I pay the outstanding amount, I have now tried calling Collections and Up-grades and even been back to Clearwater mall trying to resolve this issues without succes in fact my last call to collections I was advised that I would be listed with ITC unless the balance was paid, SO WHAT NOW!!!!! </p>
