We no longer have a super living in the building, so we have no choice but to mail it. what's confusing me is that they're claiming i owe them a month. i can't get my bank to let me set up an online account, so i have no way to check if/when they cashed my last check.Our super puts the rent bill under the door. Since April, they have enclosed a note saying it will be due on the 15th instead of the 1st due to Covid. Got the new one Friday and the note says due on the 8th and that this will be the last note and it will be due on the 1st of April. They have also asked us not to mail it but to give it to the super, who lives next door. At first they said we could either mail it or give to super and then asked us to give to super and don't mail it.
