This is indeed from SPP Inc. They are a collection service and will try to fast talk you into agreeing to a payment schedule to settle this vague, old “debt”- without providing any documentation or proof. If you have second thoughts about whether or not they are even legitimate, they will continue to try charging whatever card or account you gave them and will call repeatedly as well. Be careful, demand paperwork that proves said “debt”, and don’t let their sleazy, fast-talking “account managers” make money off of a debt unless you’re SURE it’s legitimate.
