U.S. Bancorp XXXX XXXX XXXX XXXX XXXX, MN XXXX Phone : XXXX Chairman, President and CEO XXXX XXXX After being a customer for 25+ years, and good service. I am alarmed at the lack of due diligence in resolving this major issue I am almost XXXX yrs old, but do know what I should expect. After 70 days, receiving messages that we are working to resolve. What I concluded nothing more was done on this item, everything I sent was sent back with no additional information or proof. 
This shipment was an issue within 20 minutes of receiving an email from the carrier it was delivered. There was no package at my door, I called and asked that the carrier have the truck return, my request was refused. This was XXXX XXXX, was advised I would need to call back Friday. I worked with the seller for almost 2 weeks. The seller finally requested I close the charge back, and he would locate another piece to send to me. That was refused, he was to send me copies of what he had by email, nothing was ever received. I subsequently filed the dispute. forwarded all the communication and proof, my primary request was to for the POD. I requested a copy of the signed POD and have never received it. I have repeated this since the XXXX of XXXX. It appears no one insured this package? 
The supervisor ( fraud USBank ) I spoke with was rude, and said they would call back. I requested a number so I would recognize it as I do not answer calls I don't know " well you need to answer the phone '' was her response. I want to know what specific information was received that showed proof of receipt.. I was told as long as the XXXX box was checked that I had electronically signed for it that was proof. She also stated they were not handwriting experts. Which eludes to a signature, that no one can get! 
Please send me the Proof of delivery with my electronic signature this is the only valid proof. To date that has not been obtained as there is no signature. I received a GPS screen shot sent to me as additional proof the driver was here. ( Copy sent to Bank ) That was also incorrect it shows him on a completely different street than where my apartment, this was also stated to XXXX appears he was in the complex next to mine. 
I am XXXX yrs old that was special present, within minutes it was gone. 
The Bank is expecting me to pay for an item that was not received, no POD is available the idea of a check box being proof is insanity. 
**Legal definition of POD > Proof of delivery means a copy of a signature, or other evidence from the recipient in confirmation of receipt, obtained on delivery of a postal packet ; Proof of delivery ( POD ) is to establish the fact that a recipient received contents sent by a sender. .In the United States XXXX XXXX XXXX XXXX and XXXX XXXX well as the US postal service ( USPS ) provide proof of delivery. 
Please have your legal department review this dispute, and provide the POD requested from day 1. I would hope the CEO & any officers would expect the same if they were being asked to pay for an item that was not received. 

Respectfully XXXX Received 4 notices >bank we are working to resolve your dispute, then this email. At no time did anyone reach out to ask for any additional information. Anyone can check a box, I have never had a financial institute use this method of proof. Based on the decision should not have sat or delayed the banks response for 70 days. Preventing me from acting sooner
