I've been part of this convo for a while now and it's so ILLOGICAL that QB cannot/will not right a simple line of code that allows for a delete. In this day and age of data protection it seems that a company that stores credit card data would be willing to delete that information upon user or customer request. It's not good and QB should do better. Now they're telling us to leave a message to a different department. Why not just send this thread to that department? 

Why are we always fighting here on the message boards with a company that is ALWAYS begging for feedback elsewhere?

Let's start putting this as feedback ANYWHERE it is asked - copy and paste this:
WE MUST BE ALLOWED TO DELETE CUSTOMER CREDIT CARD INFORMATION

Maybe if band together we can get it done!!
