Grooves.land review: Do not trust Grooves. Land

Almost three months ago I ordered a Nilfisk pressure washer from this company. It was supposed to be delivered interest free. I after almost a month of chasing I had to pay £48 duty before it was delivered. When it came the box was damaged and the unit would not work.

Nilfisk would not honour the guarantee as it was purchased abroad!
I went back to Grooves.Land, they would not take responsibility!
After much chasing they agreed to take the unit back and have it looked at.
This process took over a month.
Finally they stated there is nothing wrong with it and said they have sent it back.
Needless to say it has not come back and I suspect I will again have to pay duty before I get it!
Frankly I don't want a suspect machine. What i wanted was a unit that works reliably or all my money back.
If there is some way I could rate them less than one star I would.
