Carniceria La Mexicana

I bought a birthday cake here a 3 milk type and the next day we had left over more than half the cake. When I cut a slice I was chewing and a strange texture was mixed in there. When I spit it out. The cake had a gum in it. I looked in the rest of the cake and found a total of 3 gums. I contacted the owner and accused me of putting the gum in myself. I will never buy from here again.
