Product: Credit card or prepaid card

This is a copy of the email I sent to the ceo and several administrative persons at Discover Card. They didnt even reply to my email until I sent it a second time. The date we found out our credit cards were not working was Friday XX/XX/XXXX. My first call as described below was on Sunday, XX/XX/XXXX. 
Problems with my business and personal Discover Card accounts. 30yr.+ customer 2ND EMAIL-

I am writing you this evening because last week both my Discover Business account and my Discover Personal account seemed to have been closed down. Both my wife and myself were out, each in our own car, trying to get gas and our cards did not work. No notice, no email or no letter was ever sent. I have been a Discover Card customer for over thirty years and this was a shot below the belt that we did not expect. We had been both using our cards regularly with no problems until this. 
So on Sunday I called customer services. The rep could not understand why our accounts were closed. What she told me was that the business card was closed and referenced to the personal card, and the personal card was closed and referenced the business account. She told me that the departments that handle this were closed until Monday. She said I should call back then. I asked for a call back on Monday morning which is today. She said she would leave the request as needed. I was on the phone for fourty-five minutes and got nowhere. No one ever called me today, which did not surprise me.so I called and spoke to a rep who connected me to direct account review. After another thirty minutes on the phone I still dont know where I stand with Discover Card. XXXX XXXX in your direct account review department was very cordial but still could not find the reason for my account closures. He promised to call me back with an answer. 
This is not the first time I have had problems with my Discover Cards, but it is the most trying problem of thirty years plus as a customer. I can guarantee that whatever the problem might be it is not from me. My concern now is this cancellation of my cards will appear on my credit reports and I will have to dispute any derogatory allegations from Discover card. 
My contact information is: Left blank
I do expect prompt satisfaction to this problem that I did not ask for.
Yours truly, My name

I sent the following email today, Friday, XX/XX/XXXX:

Dear XXXX. left blank,
I am extremely upset at this point.  I contacted Discover card on Sunday, XX/XX/XXXX and still cannot use my account. Never has anything such as this ever happened to myself or my wife. What seems to be the problem here? 
I have never been given any answer why I cannot get into my personal and business Discover accounts. I have never been late on payments. Up to this date no one from your company has given me any answers whatsoever. 
My wife is especially upset as she was in a line to pay for items and the card was denied. She had to use a different card but felt embarrassed as anyone would be if you card was declined in front of people. I am demanding an apology. I am also demanding my cash back money which is rightfully mine for both of my accounts. 
I will soon be contacting the Consumer Financial Protection Bureau Bureau.if necessary  I will also be sending my complaint to XXXX XXXX, XXXX  and XXXX. 
Signed: My name
