Engen 1 plus and engen customer services not responding for more than a week

Engen 1 plus Bethlehem poured diesel that was mixed with water, it was first difficult to get the branch contacts and I eventually contacted customer services whom logged a complaint and reached out to the branch. They all seemed cooperative at first requiring documentation which were submitted to all parties involved in the process. It has been a week and half since documents were submitted but no response at all on the outcome. I have been following up with area manager Stanley, Costa Branch principal, Ashton from customer services but none of them are responding to my calls and emails with a resolution. Correspondence was sent via email to the following emails *** *** *** *** none of them have responded since I submitted documents.
