I returned the items I had bought before using them. The return policy of Amazon says buyers should pay only for the return fee when returning goods. I have paid for the return fee, so the seller should reimburse all the money I had paid for the goods. But the amount of money I got paid back was $514.69. The seller said he/she had deducted 10% of handling charge. But I don't think this makes sense. The seller must reimburse $571.88 to me, which is all the amount of money I had paid for the goods. So I claim that the seller should pay me back $57.19 to meet the difference.
