"Hi xxx,
Thank you for reaching out.
We sincerely apologize for the confusion.
You may disregard the phone number on the "Edit Billing Info" field as this is just a default number.
Please note that we don't pass any phone numbers externally, even to our payment providers which is why your own number is not displayed here.
We strive to ensure every customer is satisfied with our business, and I apologize for any way in which we may have inconvenienced you.
We're committed to making your trading experience the best it can be.
Should you have further concerns, please don't hesitate to reach out 24 hours a day. We're just an email, live chat or phone call away."
