My Huawei FreeBuds Headphones Box Is Lost And The Brand Does Not Help

I lost the box of my newly purchased Huawei FreeBuds 5i headset. I have been contacting the support team for about a month and asking for help. They keep saying they will call me back, but they just hang up the phone like a consoling child and never make a sound again. They didn't help in any way. What should I do? Should I throw away the headphones? How many more times do I have to call? Is it normal that you said you would come back but never came back for a month? I will not trust this brand and buy anything again. Help, support and customer contact 0.
