Eric,
Go to their job board and note the addresses of the schedulers associated with jobs. Or, call their main phone number and listen to the propts for current shoppers, select one of those names and you may have bette luck. Melinda tends to be tied up with their clients, rather than shoppers' everyday concerns.
All the best!
