First if you're going to get a test kit, get a liquid based kit, not strips as they aren't very accurate.
Next, what level of ammonia was showing when you used the ammonia remover (assume you must have had test available then)?
Now for the tough bit - the problems are almost certainly down to poor water quality. Even if it looks very clean, it can be loaded with toxins that can make fish very ill. None of these are visible to the eye and so regular testing with a reliable and accurate kit is essential. The problem is that goldfish are "messy" fish who produce a lot of waste and should grow to be quite large. For that reason they need b8g tanks with powerful filtration to do well long term This article explains their needs in terms of tank size.
Your best plan at the moment is to get a good test kit and post the results up here and in the meantime change around 50% of the water every day to reduce toxins.
For the longer term they really need a much bigger tank so I would start looking around on eBay, Freecycle and so on as large tanks can be found quite cheaply on those sites.
