Cancelation of one sided contract to Telkom

We as very loyal customers with Telkom are very disappointed in service delivered to us by Telkom. On the 3rd of January 2018 we had no lines at our business , complaint has been logged with telkom on the same day . We waited a full 29 days for service to be returned, in that time call centre found it hard to assist in information , or to help guide us on self service options. Our account manager was of no help as she promised to get back to us but on following up with her , she was either sick or on leave. No one in her department took over her cases . So we decided to opt with another company to restore service as we lost a huge amount in revenue . We wanted to cancel with telkom our one sided contract , who absolutely only benefit telkom and not the paying customer. A hefty amount was quoted to cancel said contract. We stated our case of loosing business as the telephone is the main source of clients to do business with us. They just stated that they are not liable for any loss that we might have sustained. Telkom would not meet us half way as we lost more than said penalty , we feel that we have to pay double the amount for no service rendered to us as a business.
