Woosh Help Desk tell me they cannot block Woosh phone lines from making 0900 calls they can only bar all toll calls. Telecom provide an 0900 call blocking service that allows other toll calls.
Is there a reason why Woosh can not block 0900 calls while allowing other toll calls to go through?
(The reason is a staff member accidentally pressed 0900 while intending to call an 0800 number. 0800 numbers are 6 digits long while 0900 ones are 5 digits long. If you call 0900 by mistake using 6 digits you're in for an expensive surprise - for us $20. The extra digit put the call through to a fax machine cutting off any warning message)
Hoping Woosh can change their system to block 0900 like Telecom can but Woosh say they can't. What would be the reason for this?
