double billed

I too was double billed. I signed up in March 2023 and then decided to cancel the next day, and I have the cancellation email. 

We decided to sign up a few days later. 

However, on the first set up that was cancelled my credit card was billed for 13 month @ $30/month, and the account went into a collection status.

The total with taxes is $394.50, and i have the text showing the amount of the credit.

I have called in 4 times and on the phone an hour or more each time. 

I was told I am getting the credit, and then the customer service rep credited the charges, and no credit was issued to my Discover credit card. 

My email is [Edited: "Personal Information"]. 

Please assist, for I cannot even get into my account.
