Contact Phone number for Durabrand

I heed to get missing pieces for Durabrand Dual 7C s/n: LA040FD051150. I just purchased it from Wal-mart today and the manager gave me a phone number that has been disconnected and no longer in service. I need the manual, the ac/dc power cord adaptor and the remote My PDV-722 plays for a while then starts skipping/ get blurry etc. It does this on any dvd so I know its not the dvds and I have cleaned the heads. I also can not get ahold of Durabrand! I feel this company Durabrand has plenty of room for improvements!!!!!
