constant ding and right side window switch doesn't work drivers side

What is your question?

took car to dealer to replace power antennae the broke off in carwash. lowered my convertible top to show them the real panel that closes it down wouldn't close all the way, they replaced antennae, now there is a constant ding, and my drivers front window switch wont work, It will go up and down by using the all windows button. they are not carrying Volvo after Sept 1, so they wouldn't give any help on top. Also shouldn't they have disconnected my battery before they replaced the antenna, I did not have to reset may battery, I am wondering if they caused shorts
