Query: It is a SHAM

If you buy anything from Ectaco, remember you are buying a product with absolutely no customer service. I bought a English-Norwegian dictionary software which is nothing but a crap. The password provided is not valid, it is impossible to install it and the customer service never talk to you.They ask you toe-mail the complaint, however no one ever reply regardless how many times you write to them. Finally, if you ask for the refund,they deny it. This is a SHAM product.
