I can hear you panicking and I understand your frustration but honestly, you are expecting too much of a dog that's only 4 month old. You wouldn't expect a baby to be potty trained at 6 month either, your father needs to understand that too. Please, I am not attacking you but I also feel that there is a misconception of people wanting a "puppy" and then not being able to deal with the consequences.
Okay, if you can and someone is home pretty much during the whole day you could try crate training. I didn't do it with mine but I know lot's of people, especially on this site, that had great success. If you put it in the search engine you should be able to find a lot of suggestions and tips. Again, I didn't do it because I work and couldn't keep him confined in such a small space for that long
I would recommend you taking her outside to do her business as often as possible and to only use the pee pad for peeing purposes and not for #2.
When you are not able to watch her (and you don't want to do the crate training) she should be confined in a small area, like a baby crib where there is place for just her bed on one side, and pee pad on the other side. I used the Nature's miracle pee pads from Petco. Supposedly they smell like grass- it worked well for us and I like that they are a little thicker. That way she get's used to going on the pad and if you then move her to an x-pen (no free roaming of house or room for a while without supervision) she will smell the pee pad and if she needs to go, she will go on the pad.
Consistency is key and like I said, she can't have a big, big area all for herself at that age. You should also buy a cleaning spray, such as Nature's Miracle, and make sure you clean the areas where she has gone so she can't smell the scent.
Either way, good luck and please be patient.
