This sort of rip off could easily be stopped,as could the quasi respectable practice where otherwise reputable outfits make you call them on relatively expensive tarrifs.
The telecoms regulator could require all providers to insert a warning when any call is dialled on any phone outlining the rate at which it will be charged.
No one will then be surprised when their bill says they spent £1 a minute when they thought the call was part of their inclusive free allowance.
Not likely to happen in rip off Britain though.
