Do not use credit cards for fuel

Well i now have a copy of the bill. It shows a 8000 peso charge for los Mochis and a 2050 peso charge in Navajoa. We did not stop in Navajoa. The charge in Navajoa is the staion owned by Redmax. When i go to there website, guess what? They also own Pemex 2450 in Los Mochis. She used 2050 pesos worth of fuel in Los mochis, the same amount as the bill in Navajoa on thre same day. 8000 pesos is about what a semi would take. I am thinking this may be an honest computer glitch. I do have the contact email for Redmax, so i am going to send them a copy of the statement (after the customer tells mastercard to put a stop on any tranactions in mexico for now). I can explain it all in Spanish to them, so i will give them a chance to resolve it before doing anythign else. It is still odd they told her no cash, but that could have been the language barrier.

It is possible if this station is honest, they may discover both charges went through at the same time, an impossibility unless her RV is capable of warp 1.
