Dell - Dell Financial Services Dell's Ridiculous Payment Scam Internet

On the Wednesday before Thanksgiving, Nov 25, I made my monthly payment to Dell Financial services. It was due Nov 28. They did not inform me that the payment would be considered late.  I just happened to  notice, as I clicked "submit", the date the payment would be processed  was  Nov 30, Monday. I immediately called the company and was connected to a non-English speaking person of Arab or Indian descent  who was a very poor communicator in any language. I explained to him that I had made my payment in more than sufficient time and he informed me that because of Thanksgiving and the day after, my payment would not be credited to my account in time. I asked him if he was aware the day after Thanksgiving is the biggest shopping day of the year, and not a holiday. I asked him if I would be able to purchase a computer from him on that day and he said of course to which I replied, then you should be able to process my lousy 100.00 payment. After much arguing, he agreed to waive the fee "one time". I have never had a late payment and have always paid wellover the minimum due.
 This month, I made my payment on December 24. I checked my bank account tonight, Dec 29 and find the payment has not yet been taken out of my account. I then checked the Dell account and found I was charged a 39.00 late fee today.
So, Dell, jackasses that they are, were able to post a late fee to my account in one day but could not post my payment to my bank account in 5 days. I am sure if I wanted to buy more merchandise from them today, they would have had no problem processing that either. 39.00 means nothing to Dell; but it does to me. I cannot wait to never have to deal with these people again. This is such a racket. I hate Dell.
