I never ordered from any of these companies, not even a "free" sample. I come home after being out of the country for a month and find 6 packages. I called the company and got return authorization numbers and cancelled the auto ship. I returned all 6, by writing return to sender and dumping them in the mailbox. No way was I paying about $7 a package to return something I didn't order. I contacted my credit card company which removed the charges as fraud. One credit was put through because of the returns, but only 1 out of 6 and it's been 2 months.
I just yesterday got a notice from UPS that I have a package from Vitrasun which requires a signature. Looked them up online (good luck finding any info.) and found out it has the same address as GNS and Nutralane. Telling UPS I refuse the package and called my credit card company to alert them for a possible fraud attempt.
Once they get their hooks in you, good luck getting away.
