fraudulent mails and lies

I keep receiving fraudulent calls from this company. I used to deal with them time ago but after I paid my mortgage our contract was over. At the moment I keep receiving calls from them stated that I owed them money and these calls are unreasonable because I paid everything and I can prove it with papers. I tried to contact them many times and to solve this problem but they simply ignore me. After such experience I will never recommend this horrible company to anyone!!!
