ADSL line fault

It all looked promising when Telkom started contracting out to openserve. But i see as they say, a leopard cant change its spots. I have been sitting with a line problem for more than 2 month now where my ADSL internet is so intermittent that my line drops every 5hours to 5min. I have had about 9 different OPENSERVE tech's by my premises and each one of then just keeps saying it should be fine now just test it. And not one of then know what the previous tech did. Do they not have something something like job cards so that they don't keep doing the same thing over and over. And all this time i must just be happy, smile and dint forget PAY. Pay for a service i am not receiving. Witch last time i looked was against the consumer protection act. They will sit at the street corner advertising GET YOUR FIBER HERE but when you Quary they ovver you a faster ADSL. But at the same time can't tell you when there will be FIBRE. But dont worry, the old age home a couple of blocks away has FIBRE. i dont know howm is using it. cause i am pretty shure 90% of the dont even own PC's. It is just rediculous that a problem like this can't get fixed in 2 months. what must a person do to get service.
