Purchased PUBG and Brawl Stars Accounts Not Working

I recently purchased several game accounts, including a PUBG Mobile account and a Brawl Stars account, but I cannot access either of them. Half of the accounts I’ve bought don’t even work, and despite reporting the issue, I haven’t received any response from support.

Two days ago, I bought a Brawl Stars account that also didn’t work. I’ve been trying to resolve this by reporting the problem, but there’s been no communication or resolution. I am extremely frustrated and expect a prompt response and solution. Please address this issue and provide working accounts or refund my money.
