I received a call from Freemee Debt Councellors Debt Review, and they offered a debt relief. The consultant provided me with estimated monthly calculations that will be paid to my debt. I've requested them to go and do a quotation from all my debt and come best with a consolidated amount, then we will take it from there. The consultant advised me to give my details so that when they come back with a consolidated amount, then we don't have to start from zero in case if I accept the offer. Unfortunately, they couldn't wait for the quotation. I was already registered in debt review after the call.
