1, A told you to pay first to get the machine, and asked you to pay first.
After paying the money, a so-called technical support B makes friends with you and then tells you many shortcomings of the selected computer.
3. After you are psychologically shaken, B quits and A enters. If you think the machine you choose is not good, A will recommend another machine for you. Note: This machine is usually an uncommon model in the market, mostly AMD model.
If you can't stand his bluff and buy the model recommended by him, then you are completely fooled, because the price of this model is about one or two thousand yuan higher than the market, and your money has been paid, he will never give you a cheap price.
If you resist their bluff in the third step and stick to your choice, they will give you a machine with various defects and then say it is the last one. If you are not satisfied, you can only change to another model, and then proceed to step 4. If you don't want to, you can only take the defective computer home because the money has been paid. They have been villains for thousands of years. What can you do?
