Aquasana Charge my credit card without any warning ,no email, no phone call, nothing. Austin Texas

I have a waterforlife contract for Aquasana home filter. They are suppose to charge my credit card and ship the filters twice a year. However I notice that they charged my credit account on 2/1/2017 for the filters. However I never received an email or any knid of notice of the charge. I called them and they said the filters will be shipped on 1/23/2017. That is a wooping 23 days after they had received my money. They never even sent an email to inform me of the credit card charge. This is very troubling to me. Since I did not receive any notification what would have happen if I was planning to move? What would happen if their shipping department makes a mistake and doesn't ship the filters? I beleive that all online credit charges should be followed with the sending of an email notification, followed by a shipped notification. I also beleive no company should charge a credit account without shipping the item or sending a tracking valid tracking number. SO BUYER BEWARE!! POSSIBLE SCAM!!! AQUASANA WATERFORLIFE program is a BIG question mark????
