"Rubbish!"

I attended the sleep lab in march. I was given a sleep monitoring kit that I handed back the following day. I have heard nothing since. It has been around 5 weeks. I have tried calling them for the last week or so and they never answer. The voice message box is full so you cannot leave a message. I will end up driving down there to ask a question but will have to pay parking and petrol for my trouble. Shocking
