No Telkom line

Line down since 1 February. I lodged a complaint on 11 March. I was contacted by Telkom for them asking me what the problem was as they could not find the fault on their system. I was then told that it a exChange fault and that department would contact me. up to date nobody has contacted me. My fault is still lodged and open on their website . fault no: 65CTZ010216. I HAVE NOT HAD ANY SERVICE FOR THE PAST MONTH AND HALF, BUT I HAVE BEEN PAYING MY ACCOUNTS EVER SINCE.
