I 've received several phone calls from XXXX XXXX of ERG collection threatening me to make arrangements to pay for a loanfrom 2010. I 've asked for proof but they will only send me proof if I agree to make payment arrangements. Since I 'm entitled to the information, I 've refused to make arrangements until I get the information, they 've repeatedly called my job, leaving her XXXX number. It 's very disruptive and unprofessional. I 've asked to stop calling the job but they wo n't.
