I was informed the account was normal MMR so I did it for a low price because bronze is very easy. I found out later the account gained 14 but lost 25 due to bad MMR. I asked for money, and when he did not want to pay- I told him it wouldn't be a top priority but that I would still complete it for him no problem. I finished within 3 days, easily.

Im also not sure what this 2-9 record is about. Its bronze.. literally anyone can boost bronze. Here are the games. I lost a few 3v5's where people disconnected.
