Law / Company bank account in Poland - can a company use a personal bank account? [11]

If you have a company in Poland can the bank account be the personal account of the owner or does it have to be the name of the company.

I ask because I am trying to purchase a product from a company called Roter Custom Guitars and they want me to transfer the funds into a personal bank account. They say this is normal business practice in Poland. I am not so sure.
