Ripoff. Non-existent customer service.

Product is great, but I just moved. I tried logging in to change my address and their website doesn’t work except for the parts that involve getting you signed up. There is no customer service number and the email for their help line bounces back my emails, but has no issue telling me they took my money. Why would they make it so impossible to do such a trivial thing? Don’t they want to keep customers?
