Expired product cover up

I am disappointed with Northstar Nutritionals in shipping outdated product & charging my credit card without notice. Since I received my first shipment, the company shipped 6 months worth of Benvia Gold. I had not looked for an expiration date, assuming that the product would be fresh for at least a year. When I went to open my 2nd jar, I noticed the expiration date was only about a month away.
I called the company, which had me wait until the product became available to ship me replacements. To my amazement, those too were expired! But this time, the company placed a tag over the expiration date with a year extension. WOW!! Where's the business ethics!! Of course, I called back & they credited my account. Well, last month they automatically shipped 6 jars without my asking & charged my credit card. I called them about it, & they wanted me to ship the product back. I decided to keep it, but to my embarrassment & disgust, the jars were identical to the ones that had been shipped 6 months prior. DO NOT BUY FROM COMPANIES LIKE NORTHSTAR!!!
