Incorrect Info from Telkom Agents lead to billing

My number account number is *** <br> During middle of May 2015 I upgraded my data bundle from 10GB to 20GB.<br> So for around 2 days I was using out of bundle billing. <br> <br> Once the upgrade was done I was advised that my new bundle was active and the out of bundle billing will stop.<br> Which I was fine with as I knew I have data, as per Telkom agent<br> <br> I now receive a sms saying I must pay around R2300 before the 10 June.<br> If there was no data on my package available after my upgrade, why was I advised that I now have the upgrade and I can surf the net etc. by the agent ?<br> <br> This was a problem created by the agent and I will not be liable for the cost that occurred as I was miss informed by the agent and you are more welcome to pull out all the chats I had with the agent over the net<br> <br> I have then tried to contact Telkom and the below was mentioned be the agents<br> 1st Agent Shuping Losabe, said he is technical support and he cannot help I must contact billing<br> 2nd Agent Michelle Adams said it's not mobile I must contact landline she cannot assist <br>
