Need someone to take charge

I am battling to get someone to sort out my issue. I currently make use of the Wireless Internet dial up. They busy installing fibre in my area and would like to move over to fibre however as i have the wireless contract, migrating the line does not work because of different technologies. I spoke to an agent in the accounts who advised if i take out a fibre option then we can void the cancellation fees however i need telkom mobile to advise on the same. More and more calls to get someone to assist or a senior person to assist does not help. Its going on 2 months now and still cannot get someone to help me
