No assistance from customer service

There is absolutely no service from Sony. We bought a Sony DVD player (BDV -E1600) and saw that it is not multi zone. I frequently buy other region DVD's from Amazon and Take-A-Lot and need a region free player to play these. My other two Sony blue-Ray players are both able to play other zones ( I am referring to normal DVD's and not blue-Ray discs). I contacted Sony and got a very short answer back saying it can't be done. I quieried this and got a question back as to where I bought it. I immediately answered, but it is now a week later and NO response!!! I told them it is urgent as I need to return it and buy another brand if this can't be sorted out, but even that did not bother them / still no service. All my electronic stuff is Sony, but if this is e service, I will definitely change that. Total lack of support!!!!!!
