Faulty brick

I recently upgraded from an A25 to an A56 but kept the cable and the 25w brick ,they worked just fine with the A25. the cable was used for 6 months while the brick (EP-T2510)  was used for 2-3 months . A few days ago the A56 stopped charging and it looked like a cable problem ( my usb C headphones were conecting fine ) . Next day i baught a new cable and everything seemed to work fine but now the phone is not charging again , the new cable works fine ( i tested by conecting it to my laptop and an old A32 i stopped using, the A32 also did not charge while the cable was conected to the brick ) and it looks like the brick is the problem. is there something i can do to fix it or should i go and get a new one ? I baught it from an official samsung store in Bucharest but i no longer have the receipt , can i still use the guarantee ?
