The customer service is terrible. I was looking at buying coins for episodes but saw the subscription option and figured that was a better deal. Somehow they assume that by signing up for a monthly subscription this also means that I'm agreeing to buy the whole book because that's what I was looking at before starting my subscription. They argued with me and said that there is no refund of coins. I didn't want a refund but at least acknowledge the glitch and reimburse some of my wasted coins.
