Which bank is more trustworthy?
The Better Business Bureau evaluates businesses to see if they effectively respond to customer issues and have honest advertising practices.
The BBB gave Capital One an A rating. Meanwhile, Ally received a C rating because it has a high volume of customer complaints and two unresolved customer issues.
A high BBB rating doesn’t necessarily guarantee your relationship with a bank will be perfect. Reach out to current customers or read online customer reviews to see if a bank might be a good fit for you.
Ally hasn’t been involved in any public controversies, but Capital One has experienced one recent settlement.
In 2020, The Office of the Comptroller of Currency required Capital One to pay $80 million in a settlement that said the bank had inefficient security practices, which comprised personal information of bank credit cardholders.
