Dallas Morning News "Has no record" of previous cancellation, keeps billing, won't confirm cancellation Dallas Texas

DMN was at the entrance to a home and garden show, offering free entrance tickets when you give them a 1 month trial subscription online. We (stupidly) took up their offer, thinking we were saving $20 at the event. Not so! I never used the online access but did receive 2 Sunday papers in total, and then cancelled by phone on 10/10/18.

They give no cancellation number, no confirmation of cancellation email or anything else. When I  later saw a credit card charge of $24.95, I contacted my CC company to dispute, assuming the cancellation just didn't hit the deadline. They handled it, and I thought nothing further about them... but then charges kept coming.

When I called the subscription phone number again, they "had no record" of my previous attempt, but said it would now be cancelled and the last charge refunded. I asked for refunds of previous charges, since they could see I never used the online access. He said they couldn't because again, there was no record that I called to cancel before. Just for giggles, I asked what the subscription supposedly gave me.

It was online access to DMN plus a Sunday paper delivery. I told him that I hadn't received but two of them, so the carrier is not doing their job... (That would have alerted me much earlier that the subscription was still in effect.) He had no comment about that. So here we are, now 6 months since the home show. I have to wait 21 business days to (hopefully) see a refund on my statement, because they refuse to confirm that this call has been made yet again.
