I want my paid up letters

I had 2 loans with finchoice. Paid one up in December last year and another this year January through saya recoveries coz I had lost my job. For the past few weeks I've been getting calls from Hammond poll attorneys about the account I paid in January and they insist I owe them. I contacted saya recoveries and they said finchoice recycled my account and said they will fix it. I'm still getting calls from these annoying and disrespectful people from Hammond
