Disconnection of all business mobile contracts

We are very disappointed in Telkom Business Mobile as they disconnected all four of our business contracts so we cannot make outgoing or receive any calls. The account was one month in arrears and we spoke to a consultant in the accounts department to address the issue and make a payment plan going forwards - her comment was if nobody came back to you the first time then that means we do not accept your payment plan so your phones are off until you payup. How do our clients contact us? We are losing money everyday the phones are off, how do we make online payments when we cant receive an sms. This is totally unacceptable and is targeted towards us as we are white afrikaaners. I have tried calling continuously but can't get through to a consultant or someone who can speak professionally and understand our situation.
