Ordered ecoOBD2 and now they want $24.99 every month

I saw an ad for the ecoOBD2 fuel saver pro. It said $99.00 for 2 of them. So I ordered. They sent me 2 saver pros alright.

But then they tried to charge my credit card $24.99 every month. I blocked them this month. Might have to cancel my card if it keeps up. I’m gonna try calling customer service on Monday, June 29th. Their website is crestline dynamics and they’re at 236 wirth drive in Shepherdsville, KY. Phone number is (877) 497-1092.
