2 Calls Closed, Not resolved

I have been struggling with intermittent connection on my ADSL line for almost 2 months. I have opened multiple tickets, which telkom just closes after 2 days saying the issue is resolved. The issue is not resolved. I have excellent connection and service during the evening, but during the day from 08h00 to 17h00 my internet disconnects every 20 minutes and struggles to connect for about 10 minutes each time at different speeds.<br> <br> While holding for 50 minutes to speak with a consultant I specifically said they should not close the last ticket until they have spoken to me. Big surprise, ticket was closed as issue resolved, when the issue is in fact NOT resolved. I find it ridiculous that Telkom can get away with this, just because they hold Monopoly over land lines in South Africa. Please sort out your issues.
