Good day, I trust you are doing well

Good day, I trust you are doing well. Kindly please assist me with this issue. Connect by Liberty credit solutions I received a call from Liberty credit solution claiming they work for the national credit company and that i have Home loans with high interest rates and they can negotiate with the bank to reduce interest.I honestly thought this was legit.My home loan debit order was cancelled from my bank account and now this DC partner for Liberty credit solutions has listed my account to Debit Review. I didn’t not agree to that.they did debt consolidators. Now the bank can’t remove debt review from my profile until they get a debt clearance certificate or letter from this company. Please assist
