been 2 weeks and no response from telkom

13th Jan, we get back to work only to find both our lines are not working, we cannot receive calls but we can make, I logged a fault with Telkom n te 13th and to date I have called Telkom every signle day to find out what s happening as this is our business line and very important for us t receive calls, my boss is getting frustrated as all calls that should be coming to company are going to his cellphone as our lines are not receiving calls. I spoke to 7 call center agents and 1 manager and yet to date nothing.my fault was \escalated"as I requested"
