Wargame Portal review for Shippo ‑ Simplified Shipping

Realized that Shippo was no cheaper than my Shopify Plan and discontinued usage. I thought I had downgraded my plan but then I was charged nearly 400 dollars for their "premium plan," which is literally the same cost as shipping via Shopify shipping. I've asked for a refund because I never once used the service, but have been ignored for 3 days now.
