Number calls my cell at least 5x a day! So sick of this!!! Was going to call it back but decided to search for the number on the net first. Glad I did!! Thank you all for your posts! I have NEVER done business with Sprint...EVER!!!!!!! And will NEVER!!!!! I agree with one of the comments above stating they are just looking for an easy mark that will just pay over the phone! I have to now figure out how to block their dang number from my cell! One last thing...they also call from #702-932-3860. The calls start at 7am and don't stop until 10pm!
Thank you everyone for your comments!!!! Take care and best wishes!!!

I GET CALLS 5/6 TIMES A DAY FROM THIS NUMBER, THEN JUST HANG UP..

Bryan,
            that has started happening to me too.  as it turns out.  my identity was stolen and someone did open an account with sprint under my SSN that they let go delinquent.  so the debt collector is legit.  you've most likely been the victim of fraud or identity theft yourself.  I would suggest calling sprint and asking to be transferred to their fraud management department to straighten this out.

Got two calls from this number twice in the last two days.  saying i'm delinquent on a sprint account i have never had.

This company is stupid. I've never had a sprint service provided for me.ever. so for them to think that I'm just going to get scared and start paying someone money just because they are claiming I owe it to them. Ha. slim chance. Keep trying though guys. I'll give you an "a" for effort but not a single penny.

This number calls since February everyday 5 times a day!!! Nobody answers the line when I pick up and nobody ever leaves a message!!! ACSI Debt Collector for Sprint but I dont owe money! Please make it stop. I am a stay at home mom with a little baby that needs its sleep.
Caller: ASCI Sprint.

In one month, I received 120 calls from this number. No messages and when I pick up nobody answers. I dont owe no money and wish they would stop harrassing me. I work the night shift and cant get no rest....

I never have acct . with spring.still cal me every day.

I had sprint at one time and dropped their service because of how crappy it was...This place is trying to collect every penny they can...what i did is called sprint told them that when I signed a contract with them that they broke the contract because they couldn't provide me with the services described in the contract..then told them they were in breach of that contract and I was joining a class action lawsuit...and then told them how much I would pay...just stick to the amount you want to pay and they will agree to it....they were calling me before I even got the last bill from sprint....so they aren't very smart....look up class action lawsuit against sprint and sign up if you have been cheated by sprint...good luck

I've been working to track down what company this is. There is a ACSI in Indiana, Tennasee and Massachusetts...so don't mix them up with the one that I think is most likely:

I posted the wrong number:  866-377-3956

866-377-2956 calls 4 and 5 times a day, sometimes just music, when I call back they threaten me with a large bill from Sprint.  I tried to explain I do not have an account with Sprint.  The only experience I have had with Sprint was try out their broadband piece of junk on a trial basis with the understanding it would work and that I could send it back.  I thought that was the end of that.  Now they say I owe $243.14 for a 2 day headache.  These people are on a harassment roll, hoping you will give in and send a check. They say they are Allied Collection, but they are part of Sprint.

Sorry, wrong Allied Collection listed here. We also get complaints from calls for this number but it is not the agency in Columbus, Indiana. I too would love to know who it is as we are so often confused with them and get their complaints all the time.

Keeps calling for James or Jason; person calling is a moron and speaks so fast and rudely that I'm convinced they're meth heads. Good luck with your lives ... try and find a job that helps people and remember, you have the wrong number.

I got a call at my business from this number claiming he had a Sprint account with my business name on it (I haven't had Sprint in 7 years, and was paid current). He then kept asking questions like how long I had owned the business, was I in Ohio, etc... I thought they were data mining, so I hung up.
The guy wasn't rude or anything, but it's clear they were up to no good - one way or the other.
