Bests & Worsts Reviews from Amazon

I have a subscribe & save for this. Should be #18 rolls. I haven't had a problem till the last shipment when I received 6 huge rolls instead of 18. These rolls are not convenient. They are so huge they don't work. And going from 18 rolls to 6 does not work. They should not be able to substitute different products if you are paying for a monthly membership for a certain product.
