MTN Bad internet signal

WE have been complaining from 24th August 2022 of bad signal , nothing is being done , why do we have to keep on paying for business LTE if it does not work , over a year left on the contract , so we pay every month for no service R600 down the drain , We want to cancel your bad Service , but now we have to pay the outstanding balance , WHY? For something we are not receiving. Business LTE *** NOT WORKING !!!!!!!!!!!!!!!!!!!!!!!!!
