I paid €75 more than a month ago for an allergy test. I was sent a form which I returned together with my hair sample. The first address I sent to was to a Spanish department. The letter never arrived, or so they said. I then printed out the form again and sent it along with another hair sample to their UK address. Mysteriously enough, this letter also never arrived. At this point I wrote and asked for my money back, after which there has been nothing but silence. I know I am not the first person to experience this, so stay away from this company.
