STOCK NOT WORKING

Placed my order on the 26th Aug 22 and found that one of the items arent working. I sent a mail asking for assistance. I got a mail back saying i can get a refund but will be charged a handling fee. I guess they dont check there stock before sending it out. I refuse to pay a handling fee when the item didnt work from day one. Still today i still dont know if they going to replace the item? Not happy at all
