ADSL 10meg line continuesly not working

Good day. I have been trying to get this issue sorted out since the 25.08.17 I have logged multiple calls with the call centres maybe 5-8 times a day and the problem is yet to be resolved.i am paying r799 a month for a service I cannot use! I do not want someone over the phone to assist me I want someone to come and check my line.The call centre agents all give me different stories every single time,and my calls have been cut on me as if they are paying for it.i am sick and tired of Telkom and if the issue is not resolved this contract will be cancelled due to non delivery of service. Another thing is when I have asked to speak to the supervisor my calls are being cut what kind of customer service are you'll rendering???Are you'll paying for my calls? Are you'll unable to work from home? Are you'll sitting with this frustration every single day.would you like to pay money for something every month and get nothing in return? I am paying for a 10meg line yet is getting the service of a 1meg line!
