JBL headphone issue with no repair

I bought my husband JBL wireless headphones, on Black Friday, for Christmas. The day he put on the the headphones he experienced a high-pitched buzz and clicking when songs change or while listening to audio books. I also tried using the headphones but found this extremely annoying. We returned the headphones and they said they could not refund us because we took too long to return them (this was the day after Christmas) and they would have to send them in for repairs, but only halfway through January. We returned in January and it was checked by JBL’s representative and came back as having no fault. We checked again and we could still clearly hear the annoying buzzing and clicking so we took it back. Again the JBL representative checked it and said no fault. So we sent it in a third time and they told us there’s no fault and we need to call JBL ourselves and sort it out ourselves (even though they should be calling them). We called and the number does not exist. The worst part is that some of the staff members looked at us like we were crazy when they tested the headphones, as if we are lying. In the very loud mall you can’t hear the issue but as soon as you are at home it’s very evident. We have another pair of cheap wireless headphones that don’t make this annoying sound. JBL should be better than this.
