Are they starting to really slip, or is it just our household?

In the last 10 months, my SO and I have experienced:
1) Two refrigerators delivered separately, both damaged;
2) Ordered some garden fencing and received a rug instead;
3) Garden fencing received, but box was damaged on end and vinyl wrap inside had large rips in 2 places.
4) Another order was not delivered because "home address not found" despite the fact that Amazon had just delivered here to the exact same address earlier in the week. There was no arguing with them, and they declared the package to be un-deliverable so the merchandise was never received, although credit was given.

Anyone else having issues like this? Would not be buying any Amazon stock right now.
