Sold our house in 2018. Got a letter from these guys 2 years later, claiming we overpaid in taxes and they could help us recover them. Seemed like a scam. Let the letter sit for 2 weeks. Finally called… NOT A SCAM! A month later we had a check for $1500! Granted, they took a third, but who cares? It’s way better than nothing! Call them today if you got one of their letters!
