Every month I pay my credit card over the telephone and it's an 0870 number for their automated service. Recently I remembered the website saynoto0870 and checked the number and, sure enough, there was an alternative listed which was actually 0800. I've tried it out and it takes you through to exactly the same automated service as 0870 however a thought occurred to me over whether there is possibly increased security via 0870 (for keying in credit card numbers, PINs, etc.) over 0800 or would they both have exactly the same safeguards?
