HC Deb 11 February 1948 vol 447 c61W
21. Mr. Hurd

asked the Postmaster-General what are the regulations about wrong telephone calls being charged against the subscriber; what redress is open to the subscriber; and if he will give an estimate of the revenue that accrues to the Post Office through faulty connections, the cost of which is not recovered by subscribers.

Mr. Wilfred Paling

No charge is made for a call to a wrong number if the caller reports it to the operator. The observation statistics show that the proportion of wrong numbers is approximately 0.87 per cent. On this basis the charges for wrong numbers would average about 1s. a year per subscriber's line, but I regret that it is not possible to estimate how much of this charge is actually collected from subscribers.
