Consultant Attitude at Vodacom Phoenix Plaza

Did an upgrade at vodacom Phoenix plaza in the month of May.. When came into the store to do the upgrade. The consultant named Prelene assisted me.. Did the upgrade left the store... The same consultant called me and said she forgot to charge me the admin fee and I must return back to the store.. Which I did... 2 days later she called me and said that she has given me the incorrect device and I must return it... So I advised her I will tell my wife as the device was for her... She continued to worry me the entire week like it was my fault... I the asked her that I have a 20gb data bundle with 90% discount added onto my account will that fall away she advised me that it will not... We now in October and to my knowledge I had data only to find out that it did fall away... I went into the store and she had an attitude with me and said she did not advise me that... She only processed the upgrade after 2 or 3 months waiting for the correct deal... She has no clue what's going on.
