Hypothetical question

I'm dealing with a situation and need some guidance.

ACH payment reversed after goods shipped. I've been dealing with this for about 9 weeks now and the situation isn't improving.

The amount being held/disputed is approximately $3,815. I have tried contacting customer support 3 times with no resolution.

Am I overthinking this or is this a real legal issue worth pursuing?

Illustrative response

I've dealt with this before.

Most folks screw this up by is escalating to a supervisor/manager. I'd recommend following the formal complaint procedure instead.

Have you tried reaching out to your state's labor board? They sometimes have free resources or mediation services.
