Public storage I have automatic payment every month except July and August my check comes on the first and payment comes out on the third I am on a fixed income West paterson New Jersey

 I have automatic payments come out every month out of my SS check but it did not come out in July which I did not know come August it still didn't so I called them they gave me corporates number whoever I spoke to told me she would look into it and never heard from her I paid July but now they want me to pay $259.71 . My check comes on the first of the month and they takeout on the third the money was there. It had to happen on their end. I am going to pay for August but don't think I should have to pay that much I am a widow and both my children have passed they never returned my call.
