Hello I have a problem activating an extension code that I bought here : https://www.amazon.fr/gp/product/B00I3P39IE/ref=ppx_yo_dt_b_d_asin_image_o00?ie=UTF8&psc=1, I followed the instructions and entered the code into my Sony account. From the console (plugged in RJ45) I went to Playstation store, I made "use code", I entered it, it was valid, and after having "continue" the screen remained frozen on the image for several hours without my being able to do anything. And the credits were not added ... I tried several times without success ... What to do to get my credits please? Thank you.
