I am loosing business because of Telkom Mobile

Currently I only receive missed calls on my phone. The branch office of telkom mobile advise me it is a network error. I have spend hours to the cll center without success. One of my numbers are in a suspended status, although I am not on arrears with ant payments. I am struggling now for more than three weeks to unsuspend a number from which a can make and receive calls. The number is ***.
