The link below will take you to part of the FOS Facebook pages. Looking at the site as best I can (I don’t have a Facebook account) I am not sure quite who its aimed at…especially the pictures section. Some of it seems well out of date. But anyway, it does seem to be in use to make fast financial complaints (FOS reply and ask you to contact them by private message) and also to make complaints about FOS’s service. There are several comments showing FOS in a less favourable light, there are probably favourable comments too. Presumably FOS are happy with Facebook being used for these purposes.
