It continues to give problems with some purchases and has stopped giving cashback
Good afternoon!
Thank you for your message.
Unfortunately, the Amazon PT store does not accept requests for lost cashback. Therefore, we cannot recover the money or understand the reason for the loss of cashback. However, if for some reason you do not receive cashback on orders placed with us, we will also be without a reward.
I made 3 purchases, they were not accepted, they say they don't know why, in relation to the other sites everything went well, in relation to Amazon I don't recommend it. Be very careful.
Hello!
Sorry for the inconvenience, for unknown reasons, we did not receive the commission for your orders. To support you, we have already credited the cashback to your account.
