Telkom business line been broken for two months!

My business Telkom line has been broken for two months now. I did report it - ref no: 644CRZ ********** 4/1/2018, and even have an escalation ref no: ********** 30/1/2018. When I call in to find out the status of fixing the line, I am told they dont know why the line has not been attended to. I have now been asked to phone the head office line (was given the wrong number that doesnt exist). So how can a business operate without a telephone line???? I cannot get any answers from Telkom. SO NOW????
