Worst customer service. I upgraded my warranty last month, but i noticed that it is under the wrong service tag. I called the and asked them to canceled my order and remove the service tag. After 6 hours talking to them, finally i received the cancellation email regarding my warranty. They said they removed the wrong service tag. I waited for a week and i received an email from my bank that i have been charged again for something i didnot ask for. I checked my dell account and i saw i still have the wrong service tag in my account and the charge is under that. So i called them again, they had no idea what it is. After 7 hours talking to them, they couldnot remove the wrong service tag from my account and they just referred me to another department. So, they couldnot fix what they did wrong and i still have a next bill under the wrong tag in my dell account. The worst experience, and worst customer/support service EVER!
