PUBG Mobile Midasbuy UC Purchase Not Delivered

I purchased UC from Midasbuy for PUBG Mobile, but I have been waiting since last night with no UC credited to my account. The payment was successfully deducted from my account, and there are no issues on the website, yet I have received neither the UC nor a refund.

I tried contacting support, but I have received no response. This is extremely frustrating—if players are paying real money, they should receive their in-game currency immediately or at least get timely assistance when issues arise.

I expect Midasbuy to resolve this issue immediately, either by crediting my UC or refunding my money. I need a response now!
