Supersonic is ****!!!

I paid supersonic for Vuma fibre, which during the installation process I was told they could not install in my area. I was told that I would be refunded my money, this was over 3 months ago and i have made numerous follow ups on my refund but every time I am told that they have made a follow up with the accounts admin and it will be expedited, this has been over 2months that I have been receiving the same response but never get my refund.
