I ordered a g36e once and received a g36c. Luckily before it arrived I changed my mind about wanting the longest version so ended up being happy with it
Someone there has shelf-blindness or something. They did the same to me with ICS transforM4, I got the shorter one instead, and also had kinda changed my mind by time arrived so happy with it
I message them saying they sent me the wrong one, but I'll just keep it as I can't be assed to faff around trying to get it posted and paying for it. They haven't got back to me yet
