Exxon

I had submitted a complaint a little over a month ago because I purchased fuel at a exxon station that was full of water.
I was told I would be reimbursed whatever I had to pay for repairs. I just needed to send in the receipt.
But the repairs took so long (over a month and they still didn't fix my car) that the email was automatically deleted from my phone.
I have the receipt now and would like to send it in.
It's an email but I couldn't find the companies email so I sent in another ticket.
The only option I have on here is a picture or video.

I've attached a screenshot. But I have the full email invoice from the repair shop.
