Sprint Collection agency for me...

they call me every day....telling me that they are calling "about my involvement with *company name*.  the company they are referring to is my ex's business...i never had a thing to do with it.  They tell me i need to contact them today before this matter escalates.  

They only left a message with this phone number call back once....now they tell me to call 866-677-9381

I receive multiple calls per day with this company about a piece of Sprint hardware which was stolen, and reported stolen, in October. They're trying to backbill me for service and usage in November and December.

Always shows up as unknown, but "Resolution Manager" Michael Murphy gave me this as a callback number.

I have been receiving calls from them regarding some jerk named Jerry who doesn't pay his bills.  I asked to be removed from their lists and still receive phone calls every day from their organization.  I got this number as a call back number and spoke with Heather.  I was told that they had removed my number from their lists.  Five days later I am still receiving daily phone calls from them.

Here is another address that they supposedly receive certified mail from:
ACT
PO Box 8577
Johnson City, TN

Yeah - these people called my mother looking for me - also saying that it was a personal matter.  Who are these rats?

they call me saying they have legal matters with me
they say they call (act)

they call me from this number saying they have legal matters with me
18005578133 they say (act)

That number is A.C.T (advanced call center technologies) they called me regarding a debt for my ex husband, and they provide WAY too much personal information considering we are divorced and sharing of information past that point is ILLEGAL!!!!!!!

they usually call from a blocked number, and 1800-557-8133 is the callback number provided to me by agent JoAnna James.

Didn't get details, but they said they said Melanie from 'ACT'.. I have a sprint bill and a sprint collection agency sounds about right.

Who is 800.557.8133? Thanks!
