Unhelpful, almost rude staff of Epson South Africa

I need to get a new maintenance box C9345 as indicated to me by my printer model L6550 which is quite expensive and has been a joy to use. None of the printer or electronic stores hold this part nor could even help to get it. I phoned Epson South Africa direclty to try to get help here, and the reception would not answer, those from support were totally unhelpful, and when they transferred me to sales after a whole interogation about the printer and getting its serial number, the phone just rang and then cut me off. This happened more than 4 times during office hours. The two people at technical support with whom I spoke to did not seem to care or listen to what I was saying insisting on getting serial number first, which was not needed and insisting I bring the printer in for repair, which is not required here. From the internet it seems that one can buy this part and replace it yourself. Bottom line, the support, knowledge help and basic ability to get help from Epson SA is pathetic, unhelpful, and leaves a lot to be desired. No one answers the phone, and knowledge of their people of their own products seems to be very poor to put it mildly. It is a pity as the Epson products are great. I hope someone from the EMA office or the bosses of Epson get to know about this feedback, as they need to do something about the bad attitude and almost rude people who interface with their clients.
