It all depends on the Bank that you. Plus check on why it took the refund. In fact, the refund is quick from an average of 3-4 days. Actually just given extra time for both the seller and the Bank. And accordingly, if the seller has constant operations on a refund, this has a negative impact on the company's rating for the Bank. Especially if there are disputes between buyer and seller. From my experience, the returns are realized in several ways: 1. On credit card 2. On account on the HobbyKing website. 3. Or product if not reached or was spoiled. Damaged goods was a couple of times, and some of the delivery services. Overall, the problems with the refund arose.
Sorry for bad English.

It's simply because they do not give a hoot about customer satisfaction and they play by different rules than companies that thrive on return customers. I recently bid HK farewell as a customer.
