help needed in ohio with pdls

i am in quite a jam. i have 8 pdls and have been paying every 2 weeks since late nov. i just can't do it anymore . i did pay one off completely but i can't keep up with the debits from account anymore. i did go to my bank today and asked them to stop the ach debits but that required me to fill out a dispute form. i told them i just wanted the ach debits to stop and that i had e-mailed 2 of the pdls to please stop and that the money would not be in my account, i also stated to the pdls that when they tried to take more than i expected last week it caused me to have a lot of $ in overdraft fees which i had to pay by monday so my account would not be closed . no one was paid last friday because the bank returned every ach attempt and charged me 37.50 per item . i have 4.00 left in my account after all the bank fees . sick to my stomache all week i finally went in to the bank today. these pdl people have been calling my work non stop since tuesday , plus my cell and house phone . i am afraid i will lose my job because these people are tying up the phone lines and taking up time from the people who have to answer the calls and they are told i am not there which was the truth and and 1 min. later they call back . what can i do to stop the work calls and threats at home ?
