My phone (BT landline) just rang, I picked up receiver  no  :exclamationone there but music playing. The phone remained blocked for 15-20 minutes  same music. Finally the line was cleared and I dialled 1471 and was given the following number 0208 1809293. I dialled this number and received the following message  dial the number you require followed by the # key.
Has anyone else had a similar experience ?

I think I've got to the bottom of it. I signed up to nonoh.net last week on the recommendation of a friend who has been using it satisfactorily for some time. I paid my 10 Euros for 120 free days made a few free calls and also a couple of paid calls (very reasonable) thereafter suddenly I noticed that I was being charged for local calls( supposedly free) I sent them an email on Thursday but no reply. on Friday, & I tried to access again but found I was still being charged,I put in a number to call but as soon as I saw that there was a charge I disconnected before the ring back. Yesterday some few minutes after disconnecting I got the call I mentioned. Today I tried again same result but they disconnected sooner.I looked at recent calls and saw that I was charged 20 for a 10 minute callyesterday
Can you tell me more about this Betamax group  I need to get in touch with someone there to stop this blatant fraud!

haven't used it very much perhaps half a dozen short calls. I'm not a great teleephone talker also used about 25 cents on paid calls.
