After account was hacked still being charged

In Feb 2015 my data line was hacked and someone **********ly bought a iPhone on my data line.<br> Vodacom admitted this and reversed the immediate months charges etc. However the R 578.99 for the hacked iPhone on uChoose Smart L is still being charged to my account. They want to suspend my line but they are de*****ing me for months asking for money for something was was a proven fault of theirs. <br> <br> They need to pass a credit note and reverse this package off my data line contact.
