Review of professional study provider

[wowfudge]

Can anyone recommend somewhere I can post a review of a professional study provider? The subject is a bit niche maybe and I'd prefer to post under a pseudonym but I feel strongly that I want to let others know my experience, which hasn't been great, as the study is big commitment in terms of time and money.

MN?
There is a review section.

The student room?

Their own website/Facebook page? So they know there's an issue...

Thanks @haba - I couldn't find anywhere suitable on the student room; it's very fragmented there for this particular course with few posts on some very old threads.

I've replied with my feedback after they emailed on results day - it's one of those where I guess once they've had your money and their pass rates are above average, I doubt they are particularly bothered.
