JINRONG had guilty look,they canceled account and not give explain

I saw the advertisement of jinrong China and saw many gold donation activities in October 2018. I was very impressed, so I opened an account and made a transaction.Actually, I distrustfully use my personal account to get in and out of gold. However, because jinrong China has done a lot of work and many advertisements, I think it should be normal.I followed the teacher of jinrong China broadcast studio to make the order. At the early stage, I made some profits, but later I gradually lost money. The customer service suggested that I could upgrade to a senior customer by increasing the investment and reducing the service fee.I would like to check the transaction code of Hong Kong gold and silver trading center, but later I found that jinrong China could not provide it, so I raised a question. After that, jinrong China directly closed the account, and I did not have time to keep the transaction record evidence, and the customer service staff did not reply any more.Delete account so directly, do not give the time that the user retains evidence, bring about me to want to complain very difficult now, besides do guilty conscience I can not think of other reason, why such enterprise still can exist, and a large number of place advertisement in home, because it is Hong Kong company does not have method to manage ？
