I bought an LED TV Allview 80 cm on 15.05, paid with a bank card. The product arrived to me on 21.05 with the defective display without traces of blows. I made a request for return on the same day, a request registered on 22.05. In the request I specified that I want to change the product with the same model (not waiver or refund). On 22.05 I sent the defective product back.
A week passed and I did not receive a phone, email or SMS regarding the status of the return. I order online regularly but I have never had such a failed experience.
