Why do you always get the news that the fast dog takes a taxi to get the ticket?

I used the fast dog taxi service before. Because I used the fast dog taxi service before, I have been receiving coupon messages for fast dog taxis. Fast Dog Taxi will regularly send coupon information to users who have used the service before. If you don't want to receive the coupon message again, you can cancel the coupon push function in the fast dog taxi APP.
