Rent payments

so moneygram is down that’s what my landlord is trying to make me pay by using that. i went to 6 different locations including another state all of their systems wasn’t working. i documented everything, i contacted moneygram i haven’t heard back. I showed them that i have the money and that i am trying to pay and they refusing to let me pay any other way. they said to use a cashiers check but i explained to them that i didn’t have a physical bank to use to pay and if i could use a money order as stated in my lease they are refusing. so today i am going to the post office and getting a money order because this is ridiculous. is this going to get me in trouble?? and yes i am getting a physical bank soon very stupid that I didn’t have one I know. also would like to add i only have money for rent right now, so the little bit of money i do have I want it to last me till next week when i get paid because I got sick for 3 weeks and could barely work and i’m still sick right now.
