Bad service to customers

I do make use of TELKOM as my internet provider. For 3 months I am complaining about the speed that is less than 1MBps. For the last 4weeks I have no internet service. I call almost everyday for feedback and the only thing they do is to tell my they will escalate the fault. I cannot even speak to a more senior person than they call center operator because they don't want to call someone. There is no email address for customer complaints. I can't believe they can you such a poor service. Some days when I call they even tell me they cannot find the fault I log. My line no is ********** 240. Last reverence is **********
