Upgrading ADSL Line/ Useless Service

<p>Worst service received, do you guys even know how customer service is meant to be rendered????</p> <p>I called on the 4th of April to upgrade my ADSL line from 4mg to 10mg, and they said it will take 7 days, many calls made thereafter and today is the 18th of May and still, nothing has been done!!!! Sales team says it is upgraded to 10 megs and the Technical Team tells me that it is still on 4megs and that the sales team needs to activate this for me... back and forth with no resolution!!! Telkom is the worst company ever to deal with. Can anyone help me???????? </p>
