I have made several purchases through Amazon.ca, and in most cases, I have had good service, but this last purchase, I used an Amazon hub.
The first day, the Amazon delivery service was too late to drop it off so I contacted Amazon through the chat.
After 20 minutes of speaking to customer service (in India), I was informed that I couldn't be helped because I made the purchase through Amazon.ca.
I was forced to cancel my purchases because I couldn't reach anyone or change the drop-off location.
