Query: WORST SERVICE

I have ordered this Coby CX-96 arm band radio about 1 month ago. They sent to me first time damaged Coby CX-96. I informed amazon.com about this problem. Than amazon sent to me new one Coby CX-96 for free, I was vary pleased BUT after that they request to send back the damaged Coby CX-96. I wrote that in our poor country we have not such a service and I could't send back Coby CX-96 and I ask them not to charge my credit card because it was their mistake. BUT they did not foresee my trouble and my request and charge my credit card. They have the worst service I have ever seen. BE CAREFUL NOT TO HAVE SUCH A PROBLEM WITH AMAZON!!! I AM VARY ANGRY!!!!!!!!!!
