I've issued a product refund on TurboTax two weeks ago. The status says "Your Refund status is Closed" so I asked a call but they never called me back. What can I do now?

You do not mention why you asked for a refund.   No one in the user forum can see your account or help with billing issues.   You will have to contact customer support again to see what --if anything--- they are doing.  Do not use the word "refund" in your request.  Use the word "billing" or your request will be routed toward income tax refund issues.

I have had the same issue! I have been seeking a refund for TurboTax Online for 6 months now. I was having so many issue trying to file with TurboTax this year that I decided to switch to a different service and requested by $170ish dollars back.

On a phone call with a representative following up on this issue, I was prompted to fill out a digital form (this is the first time they have prompted me to do so). When I have followed up with this form, I got the same respond: "Your Refund Status is Closed." I'm not sure what that means. 

I feel your pain.  I purchased full service on Feb. 12, 2022.  On Feb. 13, I realized that my 2021 tax filing was going to be unique and complicated this year and a TurboTax agent was not the right fit.  I called and the auto agent sent me a link for the refund form.  I filled it out, but it goes nowhere.  There is no submit button - nothing.  I left a message in my account because there was no other way to reach anyone.  No one contacted me.   I called Feb. 13 and spoke to an agent for over 30 min.  She said the Live Agent department would send me an email within 24 hours to confirm the refund.  7 days later I had received nothing.  Tried the online form again.  Nothing.  Called back and spoke to another agent today.  I was on the phone for 40 min and she told me that she had no authority to issue refunds and that the Live Agent department was investigating.  They would respond to me in 72 hours.  This is ridiculous.  I purchased a product, realized it was the wrong one, had not utilized anything to do with the product.  The refund form doesn't work.  The customer service agents have no authority to do anything.  The Live Agent team will not contact me.  TurboTax is purposely blocking my access to a refund of money for a product I never used.  There is no other number to call, no other link to follow, no other form to fill out, no other email to contact.  Shady business.

A few days ago I was asked about the refund via the private message and finally had them processed the refund. Apparently it could take 2-3 weeks so I'll post how it went once it's done. It'd been 10 months since I requested it and I can finally rest in peace

Same issue as other users. This is not helpful.

I asked for a refund for the TurboTax Premier Online on March 2, 2023.  It looks like it was taken off the bill/invoice, however, I never received the refund of $69.00 back into my checking account.
