Ideas to help me clean my carpet?!!!

El

I have tried two different cleaning machines to which neither worked. I have even had it professionally cleaned which was amazing however lasted for a month then it was dirty again. was trashed when we moved in, dried vomit, dried dog shit, food, and piss spots. My two dogs didn't help during potty trainging, currently still training both of them because my 1 year old pissed everyone and I have tried everything to get her to quite nothing works. (I think she did it to mask the other renters nasty animals). I've gotten on my hands and knees and scrubbed, hot water only, baking soad, vinegar. u name it I am or have done already trying it but I know someone out here knows what to do. it also smells really musty. If no ones ideals help most likely having to remove it and replace it to our own expense. Our la doors refuses to replace it and refuses to lower rent to help us pay for.it. at my wits in.
