Poor Customer Service Experience

I recently purchased a Hisense washing machine from Game Store at Galleria on Saturday, November 2nd. As advised by the sales agent, I registered on the Hisense website to receive an additional 1-year warranty. To ensure my registration, I went the extra mile by emailing them my receipt and pictures of the machine.

To my disappointment, I have yet to receive any reply from Hisense, despite following up and requesting feedback multiple times. This lack of response is unacceptable and reflects poorly on the customer service of such a reputable company.
