Amazon prime Did not ship items I bought through Amazon.com.

I spend a lot of money on amazon.com but I believe I'm going to cancel my prime membership and my Amazon credit card? I've never been treated so badly on the purchasing of merchandise that they never shipped me and keep dragging me along like hoping I go away, (so they make easy money without shipping me the merchandise). I'm tired of ordering $800.00 to $1,200 a month on amazon.com and they guarantee two-day delivery? (Yeah right)? there's no such thing as two-day delivery with Amazon?  I've never gotten everything delivered in 2 days; (it always comes 8 to 12 Days after I order it). I am paying $13 a month for the prime membership and I Reep No benefits that Amazon have promised me when I joined. I sent them the notification of delivery on an item and it was delivered 2- towns over from me to an address that is not on my profile of where to deliver my merchandise. I sent them the confirmation of where it was delivered and on October 1st I'm still waiting for my refund and or delivery of the merchandise that I ordered? But Once Amazon has your money, they can care less about if you received the merchandise that you paid for or not. I will be canceling everything through Amazon.com and I will no longer use the Amazon credit card and I will start ordering through walmart.com because every time I use their ordering website, I get the merchandise delivered within a day or two.
