Belgard solicitors have been sending letters to my parents house for a debt I owe for a credit card. I haven’t lived there for over two years and changed my address with the bank. Just before Christmas I emailed them to say they were sending post to an incorrect address for me and asked them to reply to my email so we could discuss payment. I heard nothing from them until today when I got another letter asking me to contact them within 7 days again addressed to my parents house. What should i do?
