VOX service is extremely bad

Please learn from our expensive mistake and don't use VOX Satellite. We pay R1600 a month for a 30 Meg line and currently it's running at between 2-7 megs with 0.25 upload. We have been on the phone to them for weeks already and our service manager George is avoiding us, everyday he calls let's the phone ring once and then hangs up and is unavailible to take our calls (SO FREAKING ANNOYING) We have been doing this everyday for 3 weeks and yes we still have to pay R1600 for nothing, even though they are not keeping up their side of the contract. We can't even run our business. IT'S A STRAIGHT UP ****.
