A gym I used to be a member of and to which I owe no more contractual obligation but are being difficult about membership cancellation still have my CC info. I changed my CC number hoping their not having my new number would prevent them from making charges. However, the CC company says that, because they have a recurring payment set up, they were able to roll over to having access to my account despite the new number.
Rather than dealing with the vendor, who have proven to me to be an unethical business practitioner, I wanted to stop their access to my CC and prevent further charges. I called my CC but they said they were not able to do that, much to my surprise and dismay.
How can I stop an unauthorized entity from charging my CC if they have account info without cancelling the card account altogether (I have a dividend mile program)?
