Sorry guys. I posted a reply earlier at noon & it seems to have gone astray.
I used
PhonepayPlus as suggested by
bigjohn
above and found all the numbers except 0906 661 4023
I called the provider of most of them, Churchcastle Ltd on 01424 797 531, and a nice lady gave me the details of what (all of) the calls were made to on the relevant dates.
I've told Mother the details but she still has NO recollection of making them.
One peculiar point came out of the talk with the lady at Churchcastle. It seems that they have her as subscribing to magazines yet she says she ONLY purchases them, as and when, from the newsagent. NONE of them are specially ordered for her. The links posted by
Dave
showed me that things may not be as they seem !
I cancelled any more mailings to mother (I hope) when I talked to the lady at Churchcastle. I'm now looking at how to block the numbers (090* and 070*) from her phone. Plusnet have been most unhelpful saying they can only block all or block none !
