ADSL line down for 4 months

My ADSL line is down once again. To get hold of Telkom on their 10210 number is a nightmare, as I have held on for over two hours on several occasions. This has been going on since October 2014. I am on for a week, off for 3. The ADSL line has been off for most of January again after only having service for a week. I sent an sms fault report as you can't get hold of anyone on their 10210 number. The sms was sent on the 23rd of January 2015, I tried to call them several times after that to no avail. A technician eventually pitched last week. I had to purchase a new modem (the 2nd one in two months). The ADSL line has been working for 6 days and once again today it is off. I called Telkom this afternoon. Eventually an employee answered. He made me fiddle with the modem to no avail, put me on hold never to return. I eventually put the phone down. Very, very, very bad service. Visiting their shop in Clearwater isn't much better, as you stand in lines for ages. Can some company please give Telkom a run for their money as we need alternatives! I don't want to deal with them any longer.
