best not to use real email addreses and CC numbers if uploading a file.
Use dummy numbers and email

Please do not post private information here. I have removed your attachment. Posting even partial credit card numbers paired with emails is dangerous. Please feel free to upload the file with dummy credit card numbers and email addresses.
