Fedex — Not delivering my packages

Fedex has had 2 of my packages in their Markham, Ontario location for a week. I reached out and they opened a case to have them delivered today, and they ended up on the delivery truck.. But are now both back at the Markham, Ontario facility. So either you just don't want to deliver my packages or you're stealing them and I'm preparing to file a claim because this is ridiculous and its not the first time this has happened. I've reached out to the store that ships with you and have advised them of this and to no longer use your company for shipping, and it seems I'm not the only one that has complained to them about it.
