Have received numerous calls from this number regarding a Sprint account.
It's a scam.
In my case, they hi-jack the account, place orders for thousands of dollars worth of equipment (mostly cell phones) and then attempt to have it clear by asking you to verify the order.
The number does not work to call back, and, when you pressure the operators -- all with heavy foreign accents -- for more detailed information, they are scripted to give you the (real) Sprint service number.
Have had repeated problems with these losers. Sprint seems incapable of dealing with the problem on their end -- we've put several blocks and verifications on the accounts, but to no avail.
Amazing that they have not been shut down yet!
I received a call from this number to verify a Sprint on-line order. They gave me 866-860-6301 as a callback number. When I called Sprint's 800 customer service number, I was assured that this was ok. I advised Sprint that they should warn their customers that they'll be getting a call verifying their order.
[***] called my wife to verify our new phone order but my Wife being the smart careful woman that she is told them she'd call Sprint herself later she did and found out it was all [***] Sprint never called her to verify anything it's a scam to steal your orders BE CAREFUL PEOPLE BE CAREFUL....
