I send a payment through my bank to pay my Dell account. I checked and it has gone through like all the rest of them. I did miss a few payments and was trying to get things back in balance. Dell did send the bill to collection, and I requested in writing for them to send me a payoff, no response. I did make a payment like I said online, and it went through. I got served a letter to appear in court about the amount owed, unless I can settle it out of court with an attorney. If Dell accepted the payment, can they still sue me?
