unusable scrap

We have used the vacuum cleaner maybe three times. He has no suction and from the outset, is super noisy and stinks.
After my first complaint mails, I was told that I had to wash the filter and to leave him long to dry. But yes not after a quarter full container?
Because I found it a bit sad that money just to waste so and dispose of the vacuum cleaner, I have him sent back to correspondence with ink pool at my expense to them. They wanted to check him. It's now been three weeks, and also do not respond to mails.
Both the product and the seller are in my opinion, absolutely not recommended.
