We are a business in Tecumseh Ontario. Whenever our regular mailman is off, which is very often, we don't get our mail. It is delivered to a community mail box despite the fact that this is a business and not a residential building. Because of this, we went to the trouble of getting keys for the boxes. When I checked the boxes, there was a cardboard inside the boxes indicating that the box is "closed" as it should have been because this is a business. When our mailman went on vacation and we had to start trying to find our mail again I went to the Community Box, and found that the keys I have no longer work. Our mailman is on vacation and we haven't received any mail for the week and I can't access the box. It is impossible to get in touch with anyone at Canada Post and I don't imagine we will get any mail this week as we will have to wait until the regular mailman comes to access the box. This is a business and we need our mail.
