The worst car rental experience

The whole experience was the worst thing ever. The bus in the airport dropped me off at a parking lot then from there I got into a shuttle bus to get to the car rental place. I was then checked in by a rep via an iPad which made me feel uncomfortable. I had to tell him all my info again and show him my credit card. I was told I had to buy additional insurance which added $100 to my total sum. if I had known this before hand I would not have booked. I then was sent to another rep to sign my contract agreement. After that I saw another rep to process my payment, but why did the virtual rep want my credit card info when we initiated and the exp date?! I felt like I was juggled around too much, the whole experience was very impersonal. I felt I did not get the value for my money. I wold never use or recommend this company again. I feel I should get a portion of my money reimbursed.
