I made a purchase over the phone (big mistake) and gave the Dell representative debit account information and change of address. Not only did she not update the address, she went ahead and made the purchase on my Dell credit card without my consent. I called Dell numerous times and not only was I told I had to make a payment, but they are including the finance charges on the statements. Don't trust Dell with anything over the phone. I am done with Dell and you should take heed to this.
