Line speed issues

<p>Two weeks ago I noticed my line speed was peaking at 2mbps , this while I am paying for a 4mbps line. Despite numerous phone calls to Webafrica and several tickets logged the situation has remained unresolved. Webafrica manage my line and therefore shoud be responsible for fixing any errors I report without me having to deal with Telkom but their response and urgency in this matter has been very, very poor. </p>
