It sounds like the letter was a summons from a court. They filed a complaint. The court gave you 30 days to response with an answer to the complaint. If you did not answer, they probably received a default judgment.
You starting to pay the debt back also limited your options as to a defense. I believe doing so, you can no longer claim a statue of limitations defense on the debt.
Wolpoff & Abramson probably won’t help you by explaining what the summons is and what you should do, etc. They already received their judgment against you and if you don’t pay on your own they could certainly garnish your wages.
You really only have two options. One, keep paying as agreed. Two, you can attempt to get the judgment set aside because you didn’t get the summons on time. If you go with option two, you should contact an attorney to discuss your case. I suspect getting a judgment set aside wouldn’t be an easy thing. Also, it may not even be worth it to try since you started paying back the debt. (Again, this may limit what type of defenses you could claim should you dispute the debt)
So, one keep paying as agreed, or two seek the advice of an attorney.
