You could have also had a dud bottle of bacteria, if it’s got too hot at any point the bacteria could have died. Try a different brand from a different shop.
The bacteria should be multiplying daily so I would have expected to see improvements by now.
I am assuming you have some kind of media in the filter (sponge, ceramic, etc) and you are not ‘cleaning it’ or changing any of it while the filter is cycling. By cleaning it I mean rising it out under the tap or heavily rubbing or scrubbing it.
Am I correct in thinking you have a betta, 5 penguin tetras and 3 panda Cory catfish? The shrimp add a negligible amount of load.
Even a small filter should be able to handle that assuming it’s got media in it but you did stock the tank far too quickly.
