Support is the real problem. They use foreign call centres and the standard of english is pretty hit and miss.

High pressure sales is also a big problem. The initial price is good and there are some good deals available. But you _must_ renegotiate at the end of your contract term. Even then, they will raise the price a few months after the start of contract so you need to chase them for price again.

I didn't have any problems with the network itself which I just use for browsing and video streaming. I don't like the political filtering but that's not their fault.
