Wrong Phone Number entered

I have made order, But Unfortunately I have entered wrong phone number.
I want to update this before they you dispatch.

Please suggest me what to do,
I have already sent email to service@living.ai to update my phone number.

That is the best thing you can do. You should have also received an email confirmation as well which has your order number and other details. You can also reply to that email in which you received and the support team should be able to reply to you and update your contact info.
