Alright so, I was developing a FTP Server on port 2121 as apart of a much larger project.
Right now the client connects and all fine The server sends a 202 response code to the client (Which means continue pretty much)
I've wiresharked the client and can confirm the packet is going through.
Curious to see what FileZilla did, I wiresharked their server response and then sent the same, needless to say it didn't work, showing that it isn't the 220 response but something else, which I am unaware about.

I asked this along time ago and have since fixed the issue, I am answering it incase anyone searches and has a similar problem.
The issue is caused by not including a carriage return at the end of requests, make sure you do that :)
