I have/had a loan with Plain Green Loans and overpaid them. I sent the letter on this site asking for PIF, refund, and to stop ACH debits/contacting me further to Plain Green Loans. Their response was as follows:
We are in receipt of your recent written complaint dated xx/xx/xxxx, and as you requested, your account has been closed from further activity. We will make no further attempts to debit your bank account, nor will we make any further attempts to contact you by phone or email.
