Lost claim from express claims box

I submitted my claim on the 10th of July via the supposedly \express claims"box inside the Brigh****er Commons gym. Nearly a month has passed and Discovery can only tell me that they haven't received my claim 'yet' and I must resubmit. Which would be great if I hadn't put the only hard copy of my claim into their claims box trusting them not to lose it.<br> <br> """
