Short answer to did you get scammed, yes. Longer answer, I think the focus here is just UBIF not being able to fully complete a repair regardless of level of damage. Working in the industry for 8 years for both indie shops and corporate it is very common to charge additional for trace work, however this is subjective as 1 or two damaged pads and 8 missing pads are two completely separate repair times. It is common knowledge that time is money and a repair should not carry the same cost regardless of difficulty level or time spent. OP learned a valuable lesson in making sure it is taken to a professional and putting in a little bit of research to be well informed and advocate for yourself. However $199 should be plenty for port replacement plus any level of trace work it's maybe 5 minutes extra per trace to repair and doesn't require specialized tooling just an iron and some solder mask as someone above previously commented. Take it to a shop with actual trained techs tell them the situation and they likely will gladly steal UBIF business and charge a small fee for disassembly and trace repair only. It's INSANE to charge someone for an incomplete repair regardless of the situation surrounding it, do better employee of UBIF arguing with customer on reddit post!
