It doesn't sound reliable. A few days ago, a number of consumers complained that they saw an advertisement of \"29.9 yuan recharge 100 yuan phone charge\" in a number of apps, but then encountered problems when recharging. After consumption, the consumer's 29.9 yuan sinks into the sea, or only receives a very high threshold of coupons. This kind of advertising is false advertising, and the merchants should be punished. In addition, Internet advertisers should be responsible for the authenticity of advertising content.
