CallCentre unwilling to assist!!!

As per the vodacom app on my phone as well as the sms i receive on my data bundle usage i still had data available on the 6th March however when i reviewed my balance it shows a usage for data of over R1 400. Upon calling customer care on the 7th March the consultant was extremely rude and refused to even log a query for me. I am absolutely disgusted at the attitude and unwillingness to investigate my complaint. If this is the level of sevice or lack thereof that i am paying for then both my contracts will soon be moved to MTN.
