TopPDF charged me twice for the same month — how can I request a verified refund?

If TopPDF charged you twice for the same month, get your account statement, transaction IDs, and the date you canceled your subscription.

They have a policy that says refunds are not guaranteed once the subscription is live or after the free trial.

Next, call customer service and explain that you were charged twice for the same amount of time. Include proof and formally ask for a refund to the method of payment you used the first time.

If they don't answer or refuse, file a complaint on Xolvie to find solution.
