Paying In Cuotas Question?


I recently made a purchase of a new mattress and when I learned the delivery was three months I canceled the order. And the company agreed to refund my money to my local credit card, and by that time only the first quota had been charged but they refunded the full amount (all quotas) is that normal and are they going to continue to charge quotas, or does that seem to be a mistake. I asked the bed store, and they tell me it’s all ok, but I can’t imagine they would basically give me the money in advance, seems like I am getting a no Interest loan without having to buy anything? I can’t imagine this is correct.
