stay away from brands that use partserve

my epson printer unit went in for a scanner error, after supposed repairs the unit comes back with a non functional keypad, booked in again and returned for the third time with the same issue still persisting. clearly nobody knows whats going on and all they can say its a open issue with epson which doesnt help anything when the unit is with them for 2 months. they still requesting proof of purchase to verify warranty even when the system print out from them is clear, really atrocius and the lady denise that takes the calls needs to be schooled on customer service
