Telkom mobile - blocked contract

My contract has been blocked for 7 days, and I still don’t know why

I received an SMS on Tuesday morning 24 July 2018 informing me that my service was interrupted.

I contacted customer services and they informed me that my complaint was logged under the reference no: ********** 17 and that a manager (Busisiwe Sibamba) would phone me as soon as possible. My contract is in good standing but no one can let me know why it is blocked, I have been on the phone everyday this week with customer care for about 2 hours daily. No one can tell me why my contract is blocked and the manager (Busisiwe Sibamba) is not getting back to me

I am a medical doctor and I am on call for eye problems in the free state, I am unable to make any calls to help my patients
