I hope you have learned your lesson about on line pop-ups.
Try this number for canceling: 1-952-908-4112- This supposed to be their payments processor company.
Never respond to internet ads, TV & Radio ads. They are all scams, especially the so-called free trials, just pay postage .
They sign you up for an auto ship program that you will not like. The canceling numbers don't work and when they do, they will hang up on you.
Google search any company you are tempted to use for any complaints. You REALLY should NOT respond to ANY advertisement.
This is true for ALL so-called "FREE TRIALS, JUST PAY POSTAGE", NO matter where you see them
Their guarantees and promises are worthless and are LIES, NO matter which product you are calling about.
If you can't get it LOCALLY, you don't need it.
