Appears that Auna and HiFi Tower are the same company. I found this out when I had to call their premium rate customer service number.
I placed an order with the company over 2 weeks ago and after not hearing anything I called them to see why my order had not arrived after the 3 days as advised when placing the order. I was then told that my order (Auna karaoke at £134) would not be delivered in time for my daughters birthday and that the company had made an error with my order. I queried how they had taken the funds but then made an error? James, the customer service advisor told me that he would investigate this and also call me back to advise what happened and what the company could do to resolve the issue for me.
Later that day the money was put back into my Paypal account and an email was received from James advising that he had put the funds back in my account, no mention of what the business would do to correct the fact that my daughter would not be getting the karaoke I had promised her or taking my funds with no exchange. I emailed them back and no response.
My advise for anyone thinking of using HiFi Tower or Auna direct is simply - don't. Use someone more reputable like the major UK toy retailers or electrical retailers.
