Rails de conversion pour lit double Princeton

So if you order this, please be aware that there are apparently 2 different bed rails, but you can't select which one you get. I originally ordered this about 2 weeks ago but I got sent the wrong rails. They were wrong because the ends that were sent to me did not fit my product. They also did not match what I ordered online. I received rails with the end in the second picture. The first picture is what I ordered and the only picture of the rails at the time. The 2nd picture with that rail end was not pictured online when I ordered [you can now see it in the grey colored rails]. I called about this and they sent out replacements to me and it was suppose to be made sure that it was what I ordered [the first picture] but something got lost in translation with the warehouse each time and they kept sending me the same wrong bed rails. The wayfair associates I spoke to each time were great and really tried to help me get this right. But somewhere in the warehouse they kept making the mistake of sending me the same thing despite the notes that were taken and the conversations that were had with the warehouse to make sure this didn't happen again. I will add that I am very disappointed in this whole endeavor. I had really hoped that this would've worked out better.
