Sprint Store By Wireless Revolution

Terrible customer service!
My moms phone stopped charging yesterday. She took it in and she was sent to this store. They held onto the phone for 5 or 6 hours to fix it. When she came in to pick it up it was charged to around 20%.
She plugged it in overnight and now its been at 1% all night and into the morning.
She took it back in pretty upset because she thought it was fixed.
They blamed it on her saying she must have damaged the port plugging it in wrong or maybe she didn’t plug it in. And it was fine when it left the store and it must be her fault. He told her «You must have done something to it… It was FINE when it left here!»
Im sorry but you Do NOT EVER say that to a customer!
Who the fuck do you think You are?!
We have been with sprint for Nearly 12 years… You’d think they would have some kind of customer loyalty program or something like that. Nope!
Month after month we get high bills and we have HAD it with sprint!
I can Not believe That is how they treat their customers!
I would Not recommend Sprint to Anyone.
They are Nothing but problems
