R180 AIRTIME DISAPPEARED

I seems to me that it is a norm that MTN can just ***** up anyone at anytime they want. They've been on strike for so long and now they are coming back with the most *********** staff I've ever had. My woman purchased R180 airtime on the 10th of August 2015. She then purchased 1gb and R10 sms bundles. She then tried to log on to the Internet and to her suprise to find out that she doesn't have even a cent remaining on her account balance. She tried to query but she couldn't since the contract is under my name. I decided to call today and find out what could have happened to here airtime. But to my surprise no one in MTN can tell us what could have happened since she doesn't no subscriptions to any company. Worse part was 4 consultants who couldn't even tell me what's wrong or what happened to the airtime no one knew \****". Now....to MTN and your CEO. ...tell me where is my airtime??...And pls fix that background sounds on call center phones it's annoying. ..nx"""
