LG lost Product quality and poor service

Bought LG BP740 player a year ago. Did not try a bluray disk until July this year and found that it could not play the disk. Took to House and home for repairs. Came back from repairs, still not working properly. Resent item for repairs. Went to fetch yesterday and tested it in store. Still not playing .I expected the item to be replaced. Phoned R&N who repaired item . Spoke to Sonet who said I must send it again for repairs. I expected that by now the item would be functional. She was not helpfull. Phoned customer service centre. first gentleman I spoke to said I should speak to the Credit Department,but no such exists. Phone rang endlessly before being answered when he \re-directed me. Phoned back and spoke to Olga who said she was redirecting me to the service Manager. Phone range endlessly until I put it down. I left the store thinking that I wil never again buy an LG product. It was a brand I trusted
