This situation sounds so odd to me.
(I'm talking about the EU law from here on, I'm not sure how it works in other countries/zones).
The customer has 14 working days to return a product and having his money back, no reasons should be provided, but the product must be returned working and not damaged in any part, so brand new (DOA situations are handled differently).
Here it comes the first question: did you asked to be refunded within 14 days from the initial purchase? It doesn't matter how dives you did with it, it counts the date of the purchase. If not, then the seller isn't obliged by the law to refund the product, instead it's obliged to repair the product. Refunding still a courtesy option (if they want), but it's not mandatory.
If you still within the initial 14 days, you have to communicate your intentions to apply for the right of withdrawal, in this case the product must be shipped back (again: brand new) and the seller has 30 days to reimburse you.
The second question: if this happened within the initial 14 days (see above), did you waited 30 days (after have shipped the product back) to be reimbursed?
You didn't provided the dates, but for what I can understand from your words:
1) Assuming this all occurred after the initial period of 14 days. You had no right to ask for a refund. It doesn't mean you can't still ask to be refunded, but in this case you need to discuss it with the seller. It can take longer because the seller is doing its interest while you're doing yours, since the laws say that the product (if damaged) must be repaired, not reimbursed. The refund in this case will only happen if a repair is not possible.
2) You "illegally" used a credit card dispute, to block/cancel a legit payment. A credit card / bank dispute is not used an instrument to refund a payment for a product that you don't like. It is used instead to block an unauthorized payment (imagine a credit card fraud) or to drawback a payment for a product/service you never received.
3) You didn't waited the proper time. Instead of trying to resolve the issue in the correct manner (and legally), you decided to create your own law (cancelling a payment after have received a product), the seller then (following the law) have denounced you.
You have the right to criticize the product if you don't like it, but you cannot call it a "scam" or a "fraud". In this whole story the one in the wrong it's you.
