No data after upgrade

I upgraded my Telkom Mobile Contract in December and ever since the upgrade I am unable to use the data. Have done 4 sim swaps (had to pay every time). Had the technician come to my house and check the settings, which was fine, and then tell me YOU MUST DO A SIM SWOP...... Still not connect. I have case number that was logged on 24 December but no one can tell me how long it will take to get the problem solved. <br> Don't use Telkom Mobile!!!!<br>
