After Hours Formal Wear

This has been my worst customer service experience till date!!!
We have visited this store twice and both the times the sales rep were so arrogant. Either because they didnt know their stuff or they were plain arrogant!!!
It was our first time and we were not explained which tux were on sale and for rental. The talk on the pricing was vague even after our requests! Their catalogue on the ones on sale and rental were very disorganised, and the salesmen just seemed disinterested in explaining anything to us.
They just go by sizes until we insisted that they measure so that we were on the same page about things.
Things were added to our bill without options being explained. We rented the basic tux which was 80 but by the time he added stuff we asked for a basic vest and bow tie (without telling us what kind of stuff he added) it came up to a whopper 150 !!!
He didnt even have samples of what we were getting. ’ The material of the vest is like my tie’ is all he had to say when asked about what the vest looked like.
Choosing a tux can be such a simple 1−2−3 process but these guys were just vague about everything! It was a @#$@ experience, i just failed to understand what the attitude was all about.
This is the first and last time we are renting a tux from them, i dont think we want to do business with them EVER!
