Trojan  -  Trojan ultra ribbed ecstasy

Hello, my boyfriend and I normally use the ultra ribbed Trojans, but thought we'd try the ecstasy this time. We went through 3 condoms and each just slipped right off. I bought the same size as we normally use, maybe the box was faulty? Can I please get a box sent to me of the Ultra Ribbed Trojans, I wont be using the ecstasy kind again. I bought these on 6/29.

Thank You
