Returned the vacuum without using it, while the refund is absolutely missing even after 14 days. Called the relevant team but no one answered the phone. Finish the online chat twice, but nothing changed. The staff there just let you know that they would report it to the refund team and an email would be sent. My concern is that since there exists a team dealing with the refund, why the customer cannot contact the team directly? Why VAX holds the refund for more than 14 days, which should be paid back to customers within 14 days? Very disappointed with this company. Since there was no "zero" star, one star has to be given as a bonus.
