Fed up

I app**** online for a broadband lte service and my area apparently was covered.... I have been paying for 2 months for a service that does not work. Technicians have been here and can't get more than one bar signal using the provided antenna. They said they would escalate the issue. This was a month ago. Calling the call centre has not helped. Contacting on social media amd I'm told that the service is ok on their side. I am done paying for a service I can't use. I get 3mb speed if I'm lucky on lte!!!!! I want Telkom to come and take back their router and antenna and I want my money refunded. I am sick and tired of the promises and stories and lies. I am done. Take back your equipment and I want a refund. And I was told I am unable to get adsl yet my neighbour below me has it.... Just a lie together people to sign up the the useless lte. I am done with all of this!!!!!
