Extremely dissapointed vox customer

I had the worst experience with Vox. I thought a big company like this would go the extra mile, but sadly no. I signed up for sattelite internet. The sales lady told me which package to choose. It was a 10mbps line. I could only read e-mails and whatsapps on this package after I told her it is for my whole house, whatching TV playing games and whatching you-tube. She then told me to go on to the 20mbps package that is more expensive. She said that it should be more than enough to sort my streaming problems out. It did not. When I logged calls, the technicians said that I would never be able to stream and that the package that I am on is not made for gaming and tv because of the latency. I then wanted to cancel the whole deal. I was told that if I do that, I would be liable for the full 24 months payment up front. So. For 24 months I paid their account in full with no internet usage from Vox. I had to get an alternative internet supplier in order to meet my needs. Thus paying double. I have escalated my issues NUMEROUSLY, but no one seems to care.
