Bad service No internet by TELKOM

I have Telkom Lte contract SIMcard and I am using for few months, since December I am having issues connecting to internet since I was leaving for holiday in December I didn't bother to lay complain,now I am back to work from 06 of January 25 I have open up a case with Telkom a lady called me and help to reset my data settings etc but I am having same issue and apparently according to her the tower where my phone is connected to its perfectly fine what surprised me is when I move 2 km away from where I am having network issue my data as well as internet works fine and I was notified via SMS to say my case has been resolved yet that's not true and I am having same problem I am barely able to use internet it's frustrating and the service provided by Telkom lakes incompetence I was compalled to open up another case while first one was not resolved, it's disappointing that as a customer one being treated like this,,,, wake upvtelkom
