Why do you need to confine this to mobile and payphones bbb, disgusting though those call rates to 0845 obviously are.
The fact is that to report something like fraudulent use of a credit card on the phone to the Police can take 20 to 25 minutes and the Police run a 24/7 service for reporting non emergency crimes.
So if you call about your credit card fraud, your vandalised car or whatever in the evening or the weekend then a 20 minute call to 0845 will be 60p from a BT landline compared to 5.5p to an ordinary 01 or 02 number or indeed zero p to an 01 or 02 for anyone on BT Options 2 or 3.
So because the Police run 24/7 its very easy to win the 0845 cost argument, even on a BT home landline. Obviously for an outfit open 9am to 5pm Mon to Fri then its only BT Option 3 customers or equivalents for whom 0845 is very bad news but the police are open all the time.
Its interesting to hear the Police blocking you over this. Did you not refer them to Pito -
www.pito.org.uk and the Met London bombings helpline where Pito/the Met did force Cable & Wireless to release a a geographic number after 24 hours. And bearing in mind that Pito advises all uk police forces on telephony I bet this is another Cable & Wireless deal. Given that Cable & Wireless are also at the back of the BBC 0870 scam and I rather suspect Cable & Wirless NGN contracts are especially vicious about the consequences of the client disclosing a geographic alternative number.
I have long delayed an FOI to Surrey Police but the news that 0845 scamming is to continue for a long time and your own recent difficulties with getting the Police to disclose the geographic number now encourage me to do so.
Or has idb also FOI'd Surrey Police already? Just how many uk governmental and quasi governmental bodies are you pursuing idb? It seems to run wider than just those bodies that you actually use the services of from what I can see?
