Withdrawal application is not processed - it has been more than half a year

Withdrawals has been slowed down from early 2023. I sent an email to contact, and the platform said it was because of a system upgrade! Withdrawal applications have not been processed since April. I sent hundreds of emails and none of them responded! In August, I applied for withdrawal again and suddenly it was approved, and mt4 was also deducted, but no payment was made!
