Thanks to Nigel for alerting us to this.
I also have been trying for several days, but have unearthed a contact number. Apparently they were "unaware of the problems" (what price a study, but what price error-checking?)
Feel free to ring: 01384 817403 - I believe the person responsible is Amy Shaw.
It is also imperative that as many people complete this study, Please note there are a few leading questions that could be interpreted or (mis)construed either way - as Nigel says: "Please have a look, think about it..."
