I asked him to send us a letter for verification and the right to dispute and he told me that his client does not work that way, that I would need to call or go online to verify the information with Castle Payday. In the same conversation, I told him 2 times, my husband is not allowed to receive personal business phone calls at his office and cell phone that is issued by his employer. This morning, - -, 2015, he called both work numbers for -, my husband. My husband proceeded to tell him he is not to call either of those numbers again. When - asked for the same information in writing, - - told - he sent it 45 days ago?? He told me when I spoke to him on Friday that I would have to do the verification by calling the creditor because they dont send out the letters in writing. Which is statement is true??
