I live in an apartment in Massachusetts. Our mailboxes are separate from the building, mounted by the end of the driveway. There is one back door to all of the boxes that the post office opens to pick up and deliver mail. For the past 4 days, we have not gotten any mail, nor has it been picked up. I happened to bump into the mailwoman today, and she informed me that the back door to the mailbox is broken and their keys no longer open it. She then told me they have tried contacting my landlord twice about the problem to get them to fix it, but they have not responded. I tried contacting my landlord, but as has been the case with every other problem I've encountered (numerous) they are VERY slow to respond. I was wondering if anyone knew if I would be able to withhold rent over this to try and get their attention so I can actually send and receive mail again, or any other steps I can take.
