cancelled account but still subscription was charged

On behalf of Canadian Quilters' Association, Ian Thompson set up a jotform account in 2016.  His email is ianthocan@gmail.com

As his tenure ended with our association at the end of 2017 we moved his information to a new account called CQAregistration and cancelled any connect with the former account.

I was informed by him that his credit card was charged for the original account in the amount of $217.28

I no longer have access to the form and forget the name even as we use a completely new form.

How do we get his credit card charge reversed and delete the unrequired form.

I have checked the email address you have shared but I can't seem to pull any account under it.

We may need the transaction details to track the account.

Please provide us with the following details:

1)Name on the Card.
2)Type of credit card.
3) Last 4 digits of the used credit card.
4) Expiration date of the credit card.
5) Date when the charge occurred.
6) Amount charged.

We will wait for your response.
