That sounds like a debt scammer to me. They love calling with vague messages and phony case numbers, to get you worried and scared.
You are being called by criminals who are pretending to be debt collectors. You and many, many other people. The same scammers will use many different phone numbers. They go to great lengths to hide who they are. The harder they make it to get a straight answer, the more crooked they are.
Here is what you need to know: A phone call is NOT legal notice of debt. Do NOT call back, Do not try to talk to or try to reason with these crooks, or tell them not to call. Any contact with them will only result in more calls, and the calls will become harassing and threats will be made. Ignore and block the calls. Here is a link to some info that should be useful. These are bad guys. They know they are breaking the law, and they don't care.
i have gotten several calls from them. they have called and left a voice mail from 713-352-1553 the first name they gave was carl water, and if i didnt pay they would come to my resident to serve me documents or to my job. well today they calling me block but leave a message stating that its my final notice and her name is maria davis and she will be out between the hours of 3pm-5pm to serve some documents. is it legit.
me as well, I actually set up payments and now cant get hold of no one. should i dispute these charges with my bank. the last payment i made to them was in aug 17

So they've been calling my cell asking for my mother with the same message about legal documents. In the messages they've left they told me they were going to come to her work and I find this hilarious because we live in a totally different corner of the country from the area of the phone number they told us to call back to.
