Expect calls dropped when concern can not be resolved....

On Monday 05 February 2018 at 9 : 30 am I recharged my Cell C number ********** 764 with R30 Cell C pay as you go air time, confirmed R 30 air time credit to the number ********** 734 via sms received from Cell C.. The phone was them locked away as it is mostly used for whats app communication, this beein said with Data blocked on the phone and the phone has been shield from subscription through dialing *13381# At 12:30 PM I had a failed voice call and being advised I have insufficient airtime....!!!! On my call been dropped thrice while advising Cell C pay as you go agents, then only getting a machine I concluded I would not be assisted with this matter.. This is not my first complaint on call charges or airtime just being depleted without reason!!!
