PLEASE EXPLAIN RETURNS POLICY BEFORE WE BUY I WANT MY MONEY BACK OR NEW DVD

i bought a dvd including speakers on the 07/11/2017. and currently there are 4 buttons that are not working on the remote. on the 15/11/2017 i called ok furniture in towermall around 10am and asked what to do, the lady transferred my call to someone who did not pick up. i dropped and called back the lady advised that i would be called back. i waited until 12pm then called back, i spoke to a guy and he advised me that the remote does not have a warranty and the speakers. i then told him that information was never explained when we bought the dvd and i asked the guy what must i do in this case. i cannot use my hard earned money to buy something that doesnt work then be told that nothing can be done. ca ok furniture train their stuff on warranty issue. i want a new dvd or my money back this is UNACCEPTABLE.
