I think this is a carefully crafted one to make people not complain but still make money. You obtain a bank of innocent looking number that are pricey, but not actually extortionate, say beginning with 085, and then you program your bot to call loads of mobiles, let it ring twice then move on. The sucker me then sees some missed calls and rings them. They get a long enough message saying basically thank you for confirming to us you are the subscriber, we will be in touch when we are in the office. it does not say who they are or give any chance to key a number. When you bill turns up you see each brief call was charged at 1.18 each time. Now that presumably means that whoever the numbers were purchased from and the company running the scam are getting a fair amount of dosh without employing anyone and You just using botted devices and add to that they get a ready made mug list so they can either sell it on or start ringing them with a different number next time so if they blocked it they will get another call. I did ask Vodafone if they knew who had these numbers but they either would not, or could not tell me and their advice was just to block them and not ring back, but unfortunately there are a couple of organisations who use 085 numbers legitimately. So they got almost 6 quid out of me between Christmas and April while I was still learning my new phone. However not any more. Also I believe that it is also sharp practice to not price all text messages the same. I did a straw poll and 7 out of 10 people had no idea, for example that the bbc text number of 81333 is charged by Vodafone at 12p a time even if you get free texts. They say they can upgrade to make them free along with a lot of others, but it will cost an extra 2 quid a month.
Reading the convoluted terms of business on their contract it seems ambiguous to me and basically allows them to do as they like from what I can tell.
I'm just wondering what happened to plain English and being fair to consumers. Most companies seem to see the public as a a cash cow. Just look at the way tv and audio is going subscription wise. Brian
