NO BUSINESS LINE FOR 1 MONTH

we have been having on going problems with our phone lines for the last couple of months. I have phoned Telkom so many times to complain and after a week they eventually send someone to fix the lines, the same story every time. the lines outside are damaged. technicians came 2 months ago to repair the lines and the problem has got worse. our lines were crackly before now our phones are dead. we have made numerous calls and not one technicians has come to see us. we run our business from our lines. we are losing business as customers think we are closed down or we haven't paid our bills. its very unprofessional and we have had enough of this. we urgently require someone to fix this problem immediately
