Trust your users, like Amazon do.

Have you ever had to cancel your credit card? You probably found that buying anything online became impossible, because they mostly paying with Credit Cards.

Yesterday I bought a Kindle book from Amazon. I went to my Kindle and downloaded the book and started reading it. Then when I checked my email, there was one from Amazon saying that they had trouble processing my card, and could I update it.

This is amazing customer service. They trust their users enough that they will still give you the product until you fix your payment system.

I believe this sort of customer service is needed more. Sure, some companies might lose some of their bottom line, but the trust between company and customer will flourish into future purchases.
