Telkom Slow Internet - Not getting what we pay for

<p>We signed up for Telkom in Jan 2017. Was quite happy with the service but the last 2 months it has been horrible. We have signed up for a 10mbps line and every evening between 18h00 - 22h00 we experience internet speeds of less than 2mbps. We are very unsatisfied with this service and before we signed up we were told our area supports up to 20mbps. I can't see what the problem is. We are clearly not getting what we pay for. We have log a call a few times and to no solution. If we knew this, we would rather have signed up with a different service provider...............</p>
