After opening the account, I deposit 500 yuan for the first time and withdraw money. The second time I deposit 10,000 yuan, and the profit is 12111. The platform froze the account on the grounds that the bank card number was wrong, and asked me to pay 12111 yuan to unfreeze the account and withdraw funds in the account. I paid it but can not withdraw funds immediately Tell me that due to the account, the card number has been abnormal, I need to pay a 20,000 yuan deposit before the account can be received. Isn’t this a routine? Doesn’t it mean that you can withdraw money immediately? The platform customer service said if 48 If I didn’t complete the deposit payment within hours, it was regarded as giving up, and I would donate the money. I paid the 8000 deposit, but I couldn’t take it out again, and I didn’t dare to pay any more. I suspected that I was cheated. If I pay the deposit, but there are other reasons for not giving me teh money. I asked the platform if the remaining deposit is not paid, what should I do with the 8000 deposit that I have already paid, the platform customer service replied that the account will be cancelled, 8000 is equivalent to being cheated
