payment of the guest much higher than what was informed in the reservation

[Alessandra883]

My guest paid more than what was informed to me on the reservation (already deducting the fees) and I did not receive according to what the guest paid (as shown on her credit card). I thought this was dishonest and I would like to know why it happened.

You will need to contact Airbnb @Alessandra883 

However will be difficult to get through with their customer services being inundated under the virus.

Perhaps contact them via social media.

@Alessandra883  I'm sure you double-checked this, but the guest always pays more than what the host receives.  Here is an example of what the guest would pay for 2 nights at one of my places:

They would pay $962.  But I would receive $750.78 ($594 + $180 less 3% host service fee).

If this doesn't clear things up, definitely do as @Helen3 recommended and contact Airbnb through Twitter by sending a direct message to @airbnbhelp or on their Facebook page.
