Incorrect downgrade of our adsl line

We relocated to a new residence in December. A Telkom technician came to install our lines on the 23rd of December. The technician informed us that we can no longer have a 4meg line because the exchange server is too far away from us. So he told us we have to use the 2meg line and we must inform Mweb that our line is no longer a 4 meg line. We informed Mweb and they downgraded our package to a 2 meg line. A few days later we find out that the previous owners of our house had a 4 meg line. We called Telkom back to complain and they changed their story saying yes it is a 4meg. So we call Mweb again to upgrade our package back to the 4meg package which they do, however Mweb informs us that the Telkom line is still a 2meg line, and Telkom still has to upgrade the line. We then callTelkom only to be told that Telkom cannot upgrade the line that this is something Mweb must deal with. So we call Mweb back and they tell us they have already upgraded our package to 4meg, however Telkom has not upgraded our line back to a 4meg line, it is still a 2meg line and this is Telkom's responsibility.<br> This is so infuriating! Telkom give us back our 4meg line!! We are paying for a 4meg package!!!
