No response from Ncube Inc

My municipal account at City of Tshwane account (7000019480)is in arrears because of many reasons but the main reason is that I received no accounts during the Covid period. I received various messages (SMS and email) over time to pay from several persons at Ncube Inc (eleanor@ncubeinc.co.za , xolile@ncubeinc.co.za , connie@ncubeinc.co.za, hendrik@ncubeinc.co.za , Chantell van Kramberg (chantell@ncube.co.za) and I always responded but never received any feedback on my proposal.
