If you try during the day then often the Dyno is running, so they will not hear the phone. If you leave a message then do get back to you. Or send an email i had a full reply within 24 hours
Keep phoning, you'll get through. Last time I was there the phone didn't stop ringing, they're always busy. If sent all morning trying to get through before.
Got through and the legends have me booked in for tomorrow!
