Amazon — Items sent were not authorized and I Amazon made a mistake sending wrong items

Address:	82001
Website:	Amazon.com

On 12/19 I went to order a Jackson Core Pillow for $21.36, Ref.# 5543286PJ00DBAL37. I wanted to add to my order but there was no way to go back and get out of check out, so I just closed it not knowing it had accepted my order and charged my credit card.
The next day on 12/20, I went into Amazon again to place what I thought was my ONLY order. I ordered the pillow and a pillow case to fit it, totaling $33.23 REF#. 5543286PK00R3N9DJ on my credit card. The next thing I know I received 2 separated boxes with a pillow in each and one included the pillow case. This was the order I placed on12/20 and was ok. I ONLY WANTED ONE (1) PILLOW AND ONE (1) PILLOW CASE. So my bill was charged for an extra pillow I did not order $21.36 !! I want this credited to my card when returned.
The next issue on my credit card bill was an order for 2 (two), At-a-Glance date books I ordered on12/21/16 Ref# 5543286PL00M7J241. But they sent me 2 2016 books!! I called the company that sent them "Pens & More" (contracted with Amazon) and the representative said return them and I would receive credit on my credit card. I did so on 12/30/16 BUT, I had to pay $7.97 for postage AND I am an Amazon Premium customer!!
The day I returned the 2 books, (12/30/2016) I received two (2) more 2016 books I did not order!!! I wanted the 2017 books! So my credit card was charged for Four (4) out of date 2016 books at 29.30 each which totals to $58.60. I want these credited to my account also!!
Now--- I have to take the time, money for postage to return these items and my charge card has the interest for these charges on it.
I would like an RMA that dosen't make me pay for postage to return these items and I will be satisfied. Once again - I do not pay return postage and credit my charge card.
Thank You
