Why the browser opens extra window for Allegro Pay

[Client:100367512]

Hi,
I'd like to highlight major inconvenience point with the site: after a certain timeout, extra browser window is opened without my consent and w/o any activity related to the payment methods - advertising me AllegroPay. I think this kind of aggressive marketing with annoying popups was abondonned by most of reputable sites. Please forward my feedback to the relevant product owners: imagine you came to Beidronka or Carrefour to buy an icecream or just came to see how much is the fish, and at some point you find in your basket some totally irrelevant thing, like a brick, a flower pot or a book by mr. Kachynski/whoever. And this happens all the time you come to this supermarket -- and you have to put it away from your basket every time just beacause the supermarket desperately wanted you to buy that stuff. 
Thanks
