Bad service

I had data bundles remaining and airtime. ever ytime i checked my airtime was being depleted while nothing was happening to my bundles when i logged on to instagram. It then eventually said that my balance was R0.00. I then recharged and bought more bundles, it continued depleting my airtime and data bundles remained constant. I then called your customer care line only to find that they are as clueless as i am we spoke for close to 45 minutes but i still was not assisted.
