inactive Call centre and passing the buck

Good day <br> I have been trying to contact MTN to confirm what is reducing my data balance and the call centre is closed according to a recording on 808. I have also attempted contacting MTN corporate and the lady advised I should email them them to do a thorough investigation. I've done so Wednesday and today I hear they are closing or have also closed down. I require assistance with this urgently as I am not able to enable data on my device without loosing data. I have checked my data usage from date of receiving airtime to day and nothing makes sence. My data balance is 0. There are occasions when checking balance then it reflects 420mb. And seconds later the balance shows zero again. This a great concern and a major inconvenience as I am not able to use my device fully until MTN can pin point and correct this. I hope that this can be resolved within the next day or 2.
