I absolutely LOVE Amazon! I have an Amazon Business Prime account.
Better than ANY other online store for the variety of items available!... 95% of all my online purchases are with Amazon!
I used to shop on ebay--- years ago... Now I only shop there when I cant get what I want, at the price I want, on Amazon, or anywhere else.
I have never really had an issue with Customer Service... any time I have had an issue, they have always made it right, in one way or another.
I believe that people who have had issues with Customer Service, are due the fact that so many 3rd party sellers have problems with their products, and a lot of them offer discount coupons...
And you have the Right to ask for a USA based Customer Service Rep.!
Or Ask to speak to a Supervisor!
Amazon will not refund your full purchase price, from 3rd party sellers, if you have used a coupon code... They will only refund the actual amount you paid... you have to contact the seller for the difference--- when you have to pay full price to re-order the item...
