Chevron Texaco review: Zero stars if possible

I have been using Chevron for my business Fuel cards for several decades. We had a hacking on our main email, and I have been locked out of our account and unable to access due to not being able to update the email address. When you call customer service, they require you to send an email for any changes to the account. Because I cannot access the account, I cannot pay my bill and are continuously accruing late fees. I sent two emails and it has been over a month, and I still have not heard anything back. So, I called the listed customer service phone number again only to be forwarded to someone in the Philippines that has no authority to help with anything. If I pay them to clear the balance, they cannot send me a receipt or statement as they will only send to the email that no longer exists due to hacking and state, they never received my letter/email that has a case number attached to it. At this point I just want to close out my account but to even do that I would have to send an email to somewhere and they will just say it has never been received. NEVER USE THIS COMPANY!
