Is the preferential purchase activity for old telecom users true or a scam?

Fraud. My dad got a house discount and went. As a result, it is said that the purchase is free. This package only has 20 megabytes of traffic, and it will be 30 yuan every month for two years. I didn't make it clear to my dad. What can 20mb of traffic on the 4G card do now? Isn't it just that my dad was tricked into spending 720 yuan to buy an unbranded, dirty and poor-quality mobile phone, which made my telecom image plummet? Where is my credibility? Now you can buy a good quality and branded mobile phone for seven or eight hundred! My dad is an old user, so it's disgusting to cheat.
