I found a service center on the Internet close to work, as a result, another one turned out to be in the same building, I handed over the column for repair (JBL Charge 3), it did not charge, of course they did it to me, but in a month, but they broke several screws that fasten the case and did not screw in new ones, and in general, where it is twisted there are different the screws broke the case (now it lets air through when playing music), in short, in the end they did what they should have done but broke something else
