I purchased a 6 month trial offer from Ancestry.com, March 2019, paid for by credit card, I requested not to keep the card on file and I never authorize automatic renewals. I was renewed in Sept 2019, I didn't catch it on my statement (my bad), was again renewed March 2020. Caught it!
Of course they won't refund me for the Sept renewal even though I didn't used it. No one should have to be auto renewed by ant company regardless of product especially when they requested not to be!
