If you never interface with their support, do you still have a problem?

The rest of their infrastructure and practices could be solid, just their support system is poor for privacy. Just don't contact them. Just because part of their stack is weak, doesn't mean the whole thing is, especially if you never have to interact with it. 

If you are still worried, purchase vouchers and that will contain any data for the account to 6 months at the shortest and 1 year at the longest cycle. Every new redeemed voucher starts a brand new 6-12 month account cycle before you dump it for a new one.
