Krogers fuel points Gas point ripoff other other

After contacting Kroger's CS supe I finally understand how they cheat you on gas pts. If you have 900 pts. from a previous month still to use and 1000 from this month, the pumps will automatically list it at 1000. If you agree to this without manually changing it, it will take the points out of this month and allow your previous months points to expire.

According to supe, it the pumps fault because their not smart enough. If they are aware of the situation, why don't they correct the problem or tell people about it. Its not right to allow people to spend $900 at your store and then cheat them out of their rewards.
