BAD SERVICE

I went to get an upgrade during my lunch today. When I get there I am given a number to wait and ended up waiting 45 minutes before I went and asked what was happening?!? There were 3 counters open but out of those 3, one lady was playing on her phone and the other lady had moved to the front door to sit and chat to another collegue. Only then did they want to attend to me by which now it is too late as my lunch hour is almost up and have to rush back to the office. AND to make matters worse I have the flu with no voice so can not even call in :(
