Is Kingston safe?

My mother purchased more than 1 million principal on the foreign exchange platform and earned more than 1 million, totaling more than 2.2 million. She applied for withdrawal, but the customer service kept asking her to recharge VIP with 300,000. We could do nothing but borrowed money to recharge, but they still refused to let us withdraw but asked us to pay taxes, more than 160,000 . We have been fooled by various reasons, and paid a wide range of objects. I guessed that all the card numbers were bought. Now all the cash we own is stuck on the platform and cannot be withdrawn.

My mother has invested more than 1 million principal and earned more than 1 million yuan on the Jinlifeng platform for foreign exchange. When we wanted to withdraw, it told us that we had to recharge Vip of 300,000 to withdraw. We borrowed money and paid it. After 300,000 recharged Vip, I remitted it many times, and then it asked me to pay more than 160,000 taxes. Is it a scam? I have been asked to pay, but I can't withdraw it. Will the big platforms deceive people's hard-earned money?
