Question is a bit vague... if WG has not mislead you in any way... then I think you've got a pretty weak case for asking for your money back.
How likely is it you'll get it back? Not very likely, if you do my own guess would be that it may well be because WG feels intimidated, rather than necessarily thinking its the right thing to do.
Usual rule... of course...is that if there are clear grounds for walking, walk before you hand money over.
I have asked for money back a couple of times, when it became clear that promised services were not on offer. Did not get money back on either occasion... but it did substantially improve service for remainder of punt in one case.. not something that I really expected.
