I had faced problem in getting service for my Acer Notebook. There was lot of delay in getting service . Under desperate situation I contacted Acer Call Center Acer Service Center but could not get proper response or commitment. The delay was badly affecting my work. After lot of internet search, I could get email id of the Chief Customer Officer (firstname.lastname@example.org) . After writing to Sudipto Ghosh, I got revert from one of staff named Sudhin Dev (email@example.com) . Thereafter my long pending problem was resolved with sped and accuracy. I also found some of the email ids - like firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com, (I think nro stands for North Region, wro for West Region, sro for South Region and ero for East Region).
I got these Acer mail ids after spending lot of time in searching and browsing. Wanted to share with you, so that you do not face the agony and delay that I went through.
