PUBG UC Purchase Unavailable for Months, Codes Expiring Soon

I’ve been trying to purchase UC in PUBG for months, but it’s been unavailable. My codes have been waiting for ages and are about to expire. This situation has never been this bad before, but for the past two months, it’s been impossible to make a purchase. I’m extremely frustrated with the lack of availability and communication about when this issue will be resolved. PUBG, please fix this problem immediately—how much longer do I have to wait? I expect prompt action before my codes expire. It’s disappointing that such an issue has been left unresolved for so long. Please assist me with this as soon as possible!
