Is good to see a retailer wanted to improve their customer service, and I can see your efforts. You are impressive !

Thumbs up for you !

I love to share my impression with IT shop sales boy with no offend meaning. Hope none taken by you.

Fancy spiky hair young men, arrogant as always (or just look like). That hardly greet customer politely. Standing behind the counter busy chatting over internet or so.

I'm not your customer and hardly will, as I don't really consumed much about I.T. product, unless sometimes I may resell some to my corporate customer which I get from distributor.

However after seeing sometimes customer may argue about product warranty & quality terms. I got some suggestion hope could be useful for you. For some basic accessories like keyboard & mouse, maybe you can give testing service like electrical department in Tesco? As OS nowdays need not reboot for it to work, is very simple and take maybe 2 minutes time of your staff. Even customer don't ask for, you can suggest to them, clarify them. This ensure your customer don't immediately come back with faulty item.

Then, be clarify with customer upon their purchase, of the product they purchased can be 1 to 1 exchange in certain period, or take time to send for warranty/ repair.

I truly understand of IT products profit margin may be way lower than many peoples think it is, and the difficulty to ensure product quality unless customer complain about them.

Lastly, some customer service training may be useful for your staff as to stand competitive in market, you need to do better than your competitor. Be a best to outshine others.
