Hypothetical question

Quick background on my situation — any input appreciated.

ACH payment reversed after goods shipped. I've been dealing with this for about 5 months now and the situation isn't improving.

The amount being held/disputed is approximately $42,868. I have tried contacting their legal department 8 times with no resolution.

Should I hire a lawyer for this or try to handle it myself?

Illustrative response

Did you send a formal demand letter? That often gets faster results than customer service.
