In April 2014 I did my weekly grocery shopping at our local Wal-Mart Super Center. Despite having sufficient funds in our bank account, Wal-Mart declined my check at the register.
I had them try to re-run my check again, to which it also declined and they printed off a receipt from TeleCheck to call their number. I was humiliated in front of my own sons and other customers, then had to walk away from my entire cart full of groceries. Upon arriving home, I called the hotline, only to be given the run-around and not able to actually speak with a person regarding this matter. My husband then called the hotline when he came home from work; he was able to somehow speak with an individual who stated they "didn't know why" our check was declined!
In July 2014 the exact same thing happened to me again (despite using checks from the exact same account previous to this). TeleCheck is a complete joke.
