Thieves! I'm ashamed for the poor people who have to work and lie to customers to sell subscriptions ... my case was simple, I had an iPhone 11 Max and I sold them for $ 800, sold I thought, big joke because in fact, they make you a plan where you buy a new phone and you deduct per month! But they don't tell you that! A few months later I phoned customer service and thought I'd found an honest person who lowered my rate! BUT AT WHAT PRICE, that of losing my first subscription plan and now paying for my new iPhone without the belly discount of my first iPhone !!!! THEFT! I contact them today and for not finding solutions they tell me we will open a case!!!! Either yes you were robbed but that's AT&T policy !!!! Humanity is gone, I'm depressed, I just have to take a lawyer and buy my phone and change for less worse if it exists !!! BE VIGILANT ESPECIALLY WHEN YOU ARE AN IMMIGRANT, THERE PROFIT AND LIES ARE EVEN MORE AT THE RENDEZVOUS !!!!!!
