My order was massively wrong today

I like Subway don’t get me wrong but today was probably my worst experience so far. I wanted a footlong Cold Cut Combo, and the girl got the footlong part right but she made me a tuna sub and even though I tried to communicate that *wasn’t* what I wanted it was too late to change the order. So I ended up with a tuna sub I didn’t really want. Still paid and ate it since luckily I like tuna salad but pretty bummed out. Guess learned my lesson and next time need to be louder and more persistent on my order, but still polite. Thanks for listening y’all.
