I was looking at my bill and noticed that I had made a call costing £6.33. I thought WTF, it was an 0843 number. Now I never call these numbers on my mobile and I certainly wouldn't call one on a Sunday at 08:45 and talk for 18 minutes. I googled the number and it seems it's a scam number. I haven't rang it! I called Orange and they have given me £7 credit. Some people have suggested that Orange are adding it to bills sneakily. Has anyone else had a similar experience?
