General poor service and waste of time

I went into the Pinelands MTN shop to check on the date of my cell phone contract upgrade. An elderly couple was in front of me, with one young man at the desk - there was a lady in the back who popped out at one point. I stood there waiting for 25 minutes with no acknowledgement and the people in front of me totally unaware how they were taking up so much time (and not caring). I left as it was taking too long. I would have appreciated some acknowledgement of time or even another person being able to help (more people came in after me in the queue. One person at the front is not enough, especially if he cannot even make eye contact with a customer!
