Apple ID was hacked and trusted phone number changed

Is there a fix for this?

My mothers Apple Account is now compromised, trusted number removed and replaced with a number unknown to me. Password also changed.

I found this in community, but it is not helpful because the second step requires knowledge of new trusted number added by hacker which I obviously don't know.... Any help appreciated.

1. Go to iforgot.apple.com and enter your Apple Account email address. 
2. You will then be prompted to confirm the trusted phone number on file, and will only see the last two digits of the phone number, as a hint. Confirm the phone number.
3. You will then be presented with several different options on how to regain access to your account. These are all the options we just covered in the last section. (using a trusted device, the Support app, and verification code sent to phone number) At the bottom of the page in blue, select ‘Can’t use any of these options?’.
4. On the next page, at the very bottom, select ‘Continue Anyway’. This page briefly warns you about the estimated recovery timeframe to regain access being longer.
5. You are then asked for a verification code to be sent to your trusted phone number. Select “Don’t have access to this number?” if you don't have access to your trusted phone number. Before account recovery is successfully set up,  you will be asked for a new phone number and will have to enter a verification code that is sent to it. This then becomes the phone number associated to the account recovery request. 
6. Now you will be prompted to enter the verification code sent to your Apple Account email address. Enter the code, or select “Can’t use this email address?”  If your Apple Account email address ends in @icloud.com, @me.com, or @mac.com you will not be able to receive this verification code.
7. Next, if applicable, confirm the primary payment information on file with your account, or select “Don’t have access to this card?"  If the card is no longer valid, has expired, has been reissued, or is being pulled from Apple Pay, then you cannot use this option. This means that even if you still have the card or know the card information, but it is no longer a valid card, just select that you don't have access to the card.

Can you not change it back?

Are you not still logged in on an Appe device?

If you are, you can update the trusted number.

click here ➜ https://support.apple.com/en-us/122621

If you are not logged in to the account somewhere, and cannot get the Two-Factor Authentication code on a device, and have no access to the trusted number, then there's not much you can do unfortunately.

So that's just your Apple Account. what about your devices, Can you access those in any way?

Can u help me

I've been trying to, have you done anytihng I've suggestd already?

We have no access to your account here, so we can;t direclty do anuthing about that. You need to talk to Apple Support directly about that, but if you still have access to your devices, there may be things you can do. but again, you need to tell us what if anytihng appears on your Apple devices' screens currently.

So they did more than just change the trusted number.

What exactly did they do? Seems like a big part of the issue is missing here.

They can't lock you out of your device. They can set the device to lock mode, but if you know your own passcode you can enter it and unlock it. They can't remotely change the passcode.

What do your devices currenlty display onscreen?

If you want help, you are going to have to be very detailed and clear about what is happening on your devices.

Remember that the people on this forum are users like you. We are not Apple and have no more ability to actually do anything with your account than if you were to walk out onto the street, stop somebody and ask them to help you with this. What we can do is provide you with advice from experienced helpers like Phil0124 about things that you need to do.

The trusted phone number on the file is not mine, i can only see the last two digit which is not mine
