UK broadband

I'm grumpy about my ISP, Nildram.

My current contract with them is 512kbps broadband service for 22.99 pounds per month. (If you live in Japan, South Korea, the United States, or maybe other rich countries, you'll be surprised by hearing this. But this is true. In UK, this is the standard price for as slow as 512kbps Internet connection in the 21st century...)

Before I knew, Nildram began a new broadband package with 2Mbps and 15.99 pounds per month (though customers will be charged more to download more than 1GB per month, which is I'm totally not sure enough for my heavy usage of the Internet). They never told me about this new service.

What's more, if I transfer to this new service, I have to pay one-off fee of 39.99 pounds! What the hell is this price system? (And this is the explanation they offer, which totally doesn't make sense.)
