Faulty cloud nine

I bought a cloud nine from Partners hair design in October 2019 which I had a year guarantee, which I had 2 send a email for a extra year 2021 , I send to them an email. A month ago my Cloud nine was becoming faulty so I'm so disgust in your service level supp****. And not asking for money back but merely assistance with a fixed product that was sold to me by partners.Partners live by selling faulty brand items .Partners have a high code and conduct of being the best in the industry .Yet fail to mention that no assistance can be given. Seeing that the merchant is closed it should have been communicated to customers. They had to register me on their system but they did not. I sent an email to the cloud nine email address and they said they do not find an account with my details when I registered myself online...I do not understand how cloud nine is such a good product but their customer service is absolutely the worst. I went to the store I bought it from canal walk partners hair design all they told me was to send an email to the email address on the box with absolutely no help at all I was confused by the way I was treated I was fogged off by a lady that works there.
