Purchased a membership for Sam's Club, spent months making phone calls trying to get a redemption code that actually worked. Sam's couldn't help because they said I needed the code from LivingSocial. Today I wasted more time making phone calls, ended up with a "customer service" agent in India who could barely speak English. Promised for the 3rd time that my case would be "escalated". All this to save $10? What a joke.
