Quick to disconnect but can't switch back on

Disconnected my grandmothers electricity and charged R1400 reactivation fee + account balance = R8500 which she paid the same day the power was disconnected. Was told to pay before 15h00 and send proof of payment which we did. 2days later and no electricity has been activated at home yet. Poor poor service. You can't even call the call center because I've waited 3 hours before the line just cut.
