Bottom Line
Sainsbury's Bank sits in the middle of the pack for complaints. They are not the worst, but they are not the best either. If you are already a customer and things are working fine, there is no particular cause for concern. But if you are choosing a new provider, it is worth comparing them against lower-complaint alternatives.
