Bad Service from Telkom / Openserve

Bad Service - - -Telkom my landline number is ***, I requested that my landline number must be moved to Fibre (VOIP ) on the 28th of April, I already have a fibre line with you, my landline was immediately disconnected on the copper side and there is currently NU tone on the line and on the fibre side there is only blow on the line, I have contacted the Call Center already on the 4th of May ( no joy ) and I have reported the landline and it was cleared without anybody attending to it - in my view this is very bad service..................................................................
