Help Settling A Collections Debt!

I really do not know how you all got in trouble with tmobile, I read a lot of blame being directed at Tmobile, and so on. 

I got in trouble with a CA, Tmobile, lower credit score, higher interest rates, etc because I did not pay the bill. 

I was not in a good place at the time and just swept it under the rug. A few months later the consequences happened. 

I am in a better space now, and I owe $632.43 to a collection agency, and I would love for tmobile to recall the debt from the CA and allow me to pay them in full today. It was not your fault, Tmobile, I screwed up, I own my mistake. 

I already wrote Mike Sievert a letter today, and let's hope that works. The collection agency is offering me a deal of 50% off, but I don't want that, I owe $632.43, not $316.22.

Naturally, I am not all about righteousness and such, I want to pay in full so they remove the information from the credit reports, duh! 

I am just not about pointing fingers at anyone or anything when it was my own lack of control over my finances. I am not going to make up stories, I know you all did not and are not making up stories, I am just saying I will not do that. I did this. Please have mercy, and help me solve this ;)

Gracias.
