Bussiness Service Shocking

We had a switchboard installed over a year ago but have not had any joy until today with and service related to the switchboard. No one knows how to program the board We have two lines that have not work for a month without being unusable for the next two months I have been sent from pillar to post to have this repaired but still not working I have requested a pole as my line is in my neighbor's tree which he would like to cut down but still waiting I cancelled a line on the 28 May 2015 with the ADSL and gigs and they only cancelled the gigs and ADSL so still being charge for a line that was cancelled I want credit for the times that the lines where not working and now they are telling me they cannot see when they are not working. I need to know how do they charge you service fee if they cannot detect if there is a fault on the line I am appalled at the service that I have received as a business owner and cannot believe that Telkom will keep a lot of clients if this is how they deal with complaints I want my account sorted out so that I can pay it and have my account reactivated please I want to return 4 extension hand sets I want only one extension and 2 hunting lines on the switchboard I only want two numbers for my switchboard and want 2 lines cancelled I want someone to come and program my night line and on hold music I want my line to be put under ground because I have been left with the copper cable to have it done and still no one has returned to complete that either I really need this sorted out as it is affecting my credit rating and I feel it is unfair to us as consumers to be listed because customer service in Telkom suck's
