Anker soundcore no power

I bought Anker soundcore in May, I was very happy with product, sound was amazing. I never have fallen yet, but it suddenly stopped working when I was listening to it on high volume. Red power button is on when it’s charging, but there is no power and no sound at all.
Actions I have taken so far:

  1. pressed power button for 30 seconds
    2)pressed Bluetooth button for 8 second
    3)pressed all buttons at once for 30 seconds
    4)tried to plug it with aux cable
  2. unpaired speaker from Bluetooth list in my phone
