You got that call, too, right? Deduct money within three days from the moment you agree. It's just that when you receive the contract, if you don't want it, you still have fifteen days to think about it. During this period, you can cancel and the money will still be returned to you. I suggest you don't want this, but mine will be returned. After reading the contract, there are too many conditions, and it is estimated that something will happen, so it will not be exchanged easily.
