ANGRY CLIENT

I just called Dunns, now in Eldorado, I spoke to a gentlemen there, I didnt get his name, i wanted to enquire on a style number, he advised me this i am breaking up while i am on the line, and soon the phone drops, not sure did he put the phone down in my ear. Once the phone dropped i called back again, and the phone was just ringing, i called back twice with no answer, i tried a third time and the phone was on voice mail. WHAT TYPE OF SERVICE IS THIS...
