Generally speaking, that is exactly what you get. Any misunderstanding is down to bad advertising and lack of information, or inflated expectations.
If you pay about £5 a month, you can get an ADSL line with a contention ratio of maybe 250:1 and a speed of "up to" 8 or 24Megs. The actual speed depends on your distance from the exchange, and will usually be very much lower. In many cases a reliable connection will be technically impossible. The 250:1 contention ration means speeds could legitimately drop to barely dialup speeds at peak times, so often traffic shaping is used so that browsing speeds are unaffected by heavy file sharers.
If you pay about £1000 a month plus £10,000 installation costs (depending very much on where you live), you can get a fast leased line with zero contention. It costs that much, because someone has to lay the fibre which involves digging up roads and bribing council officials.
For varying amounts in between those extremes, you can pay for lower contention. Basically, the only reason you can get cheap broadband is because you're sharing the bandwidth with other people. The more you share, the cheaper it is at the expense of slower peak-time speeds.
If someone would just shell out a few hundred billion pounds, then we could all have fibre to the door. Unfortunately, nobody wants to pay for it.
