I hung up. First of all, I said I found a good unit. As a result, I hung up for a long time. Later, I hung up. It was packaged by TM, which is the proof of the person in the institution returned by the user. Then I put my certificate on it, and the other party also took some money. So mine is a little short. The communication salesman asked me to complain about his family in official website, and then it was fucking over. The communication company said that the money had been given.
The above personal experience. I hope I can help you.
