I pay my bill via debit order on the v5th of every month

I pay my bill via debit order on the v5th of every month. my last debit order was on the 5th of June, verified by the contact center agents. All my numbers under this contract have been disconnected. I simply cannot understand why. Please have this matter resolved and I require feedback as well as compensation for the days i have not had services from Telkom. It is inconvenient to leave home and have no for of communication in case of emergencies.
