Not solving my problem

Good day, <br> i have had a problem with telkom for the past 2-3 months, i have a 4Mb uncapped adsl line with telkom.<br> all of a sudden my line started getting congested after 16h00 in the afternoon and weekends, it is so slow it is unable to use. i have logged a call with telkom in feb 918CTK090315, that was my first problem call, it was closed saying it was solved, technician visted a month ago the site, didnt check my line saying that i was congested and he will send it to another department, after that someone contacted me saying the port was moved, that didnt help at all, infact it was slower, i get over 500 ms, it is not what i expected, we are in april now, and still nothing solved, i hold on for 40 minutes on the phone and then i either get cut off or technician tells me it is escalated... i have tried the support chat, that doesnt help either, i dont know what to do? i am paying +- R700 a month for nothing atm. i need to work after hours, and its to slow, currently i use a Vodacom 3G. it seems that telkom cant solve a simple problem like this. i would not suggest people to use adsl as i am in the IT industry and was a big fan of ADSL overall as it is faster than anyways (Was...)
