CONTRACT BLACK FRIDAY DEAL

I've recently upgraded my contract to a 300GB Home Internet Price Plan top up. I asked the agent in question whether I will receive and make calls (I have done this numerous times in the conversation) and he said yes to all the times I have asked.

I am currently in the situation since last week with no ability to make calls (which my job requires me to) which affects my income. I have called customer care and till now waiting on a solution as 'they are busy looking into it'. Could someone please fix my issue or I will cancel my contract
