What is wrong with Telkom`s internet connection

I have a HUGE problem with Telkom for the past wee****. I upgraded to 10Mbps Uncaped ADSL 2 months ago. Everthing was all good untill a week ago 20 March 2018 when I suddenly have no connection at home. I phoned Telkom and after various and continuous calls and explanation and frustrations they sent out a technician 4 days later 24 March it was confirmed that some previous Telkom technician used my line to do some tests on one of my neighbours. Afterwards my ADSL Modem was working again (Lights on modem shows the green on the correct spots) BUT no Internet connection. I phoned again on Monday morning 26 March for assistance and one of the operators ask me to reset my modem. After that did not work she ask me to log into the internet and google 10.0.0.2 so that I can check my connection. Really? While I`m having an internet problem already with Telkom and they still want me to google on the internet? With what Internet connection?............ This morning 27 March I phoned Telkom again and another operator told me to change my wifi name and password. So he did this on his side and all will be good as I will now have connection. But still no connection. Question.......What the **** is wrong with Telkom`s wifi connection?????? I pay a lot of money for no service!!!!!!!! REALLY TELKOM!!!!I`m really disappointed!!!! Don`t know what to do anymore!
