social bundle/social ****

on the 29th January I recharged with 380 and bought social bundle for 350, ive been using to my knowledge ive been using the free cell c to cell c minutes till today when I got cut off and called cell c customer care and was told my 300 minutes had depleted. the lady couldn't even explain to me how they got depleted cause am sure I didn't even use a 100 minutes of the bundle to call other networks. so basically am left with 500 minutes to call cell c to cell c minutes which tells me that cell c charges the cell c to cell c calls to those 300 minutes. I want a detailed report on what numbers I called from the 29th to today that are not cell c. and the duration on those calls. this is the second time I got *****ed by cell c. am enough its either u return my minutes or put my 350 in as airtime.
