Lao Lin is a retired worker. He used to be a senior electronics engineer and has an in-depth understanding of various high-tech products. However, after retiring, he felt a little lonely and a little disconnected from the development of new technology.
One day, Lao Lin received a mysterious **, who claimed to be a staff member of a charity, claiming that there was a free travel opportunity for the elderly. Lao Lin was attracted by this opportunity and decided to participate.
During the tour, Lao Lin and other elderly people were taken to a luxurious venue. A lecturer in a white lab coat walked up to the podium, holding a seemingly ordinary bracelet in his hand, but on closer inspection, it was inlaid with a miniature screen and various sensors. The instructor claims that this bracelet is able to monitor the health status of the elderly in real time, including heart rate, blood pressure, blood sugar, etc., and can also view various data and health recommendations through the miniature screen on the bracelet.
Lao Lin was very interested in this bracelet, and he asked the lecturer if this bracelet had other functions. The lecturer smiled mysteriously and took out another seemingly ordinary mobile phone, claiming that this mobile phone can be telemedical, can communicate with doctors through **calls, and can also use the app on the phone for health management and **shopping**.
Lao Lin was deeply attracted to these "high-tech products", and he decided to buy them. However, when he signed the purchase contract with the instructor, he found that the contract did not clearly state the warranty and after-sales service of the product. He was a little uneasy at first, but the instructor told him that these products were very high-end tech and that there was nothing to worry about.
After returning home, Lao Lin couldn't wait to use these "high-tech products". However, he soon discovered that the products were not as amazing as the instructor had described. The data on the bracelet is not accurate and often malfunctions;Apps on your phone also don't work properly, and there are frequent stuttering and freezes.
Lao Lin began to suspect that he had been deceived, and he decided to check the ** and authenticity of these products. After some investigation, he found that these so-called "high-tech products" were just ordinary commodities and there was nothing magical about them. Moreover, the ** of these products is much higher than the market price, and the 100 help plan is all to deceive the elderly.
Lao Lin was very angry and disappointed, and he realized that he had been deceived. He immediately contacted the charity and the lecturer to ask for a refund and return. However, the other party refused his request for various reasons. Lao Lin felt helpless and helpless, his money had been wasted.
What do you think Lao Lin should do?
