Telkom not soring out a landline that has not been working after several escalations

My landline has not been working for over 2 months now. I am exhausted of reporting this fault and all I get it empty promises ( I received 6 sms saying they understand my frustration, which clearly they do not) and no actual assistance, Telkom still bills me for a landline that is not working. I made my first escalation and was ensured a technician would come out and see to the problem. I cancelled arrangements I made that day and Nobody even had the decency to let me know they will not be coming out to fill their promised made. Terrible service! It all good and well to sign a contract and pay your bills but telkom does not keep their end of the deal by providing good service! Im so fed up and sick to the stomach of telkoms lack of concern for their customers who are their bread and butter of the company.
