The ikea employees are so unkind, always ok, I don't know if this is normal. I also work in a store, but we really shouldn't be like that to the customer.
+ that I have returned a complaint today but they really do not take it back.
It is about a plaid that is very poor quality and leaves a lot of pieces loose, they say to me that some people disturb it and some do not.
