DSE was just as bad. One day at the counter I got a bit annoyed & asked the guy if the sales staff got any training in the application of the CGA. That was when they were trying to up sell me with an extended warranty for something that should last at least a few years.
I had something still within warranty from them once, which they refused to assist with because I could'nt provide the invoice, yet could give them exact time and day it was purchased (CC) - they claimed they didn't hold records for anything except phones and TVs!! Wasn't worth my dealing with manufacturer direct (Was going to cost $60 to ship item and a new one was $180).
Never dealt with them again after that.
