Sony is not into sustainable customer satisfaction

Sony seems to make it as difficult as possible to reach them for product accessories. no contact details. only local stores who are not interested in providing contact details of Sony sales people - only to ll stock in stores. nowhere on the websites could i find a contact number or e-mail address to inquire where to get a cleaning kit/cartridge for a digital photo printer. seems that once you bought the item, they do not like to ever hear from you again unless you buy the next. and their local stores keeping their stock and products can't give a damn. i wonder how this operating model works for them.
