Pokemon X/Y Pokemon Village Banette Frustration!!!

I have spent about 2 hours every day since last Wednesday trying to get a freaking Banette from the stupid shaking garbage cans. And each day I find one of the shaking cans I save infront of it so if I fail I can start it up and keep trying. So that's 8 hours of trying and no luck. Just freaking Garbodorsm now if it was a shiny one then I might catch it lol. BUT I DONT WANT THEM I HAVE SEEN LIKE 100 OF THEM. I have done 4 hours in X and 4 in Y AND NOTHING. Banette is the last Mega Pokémon I need. I have ever other freaking one you can possibly get at least so far, unless Game Freak adds more later lol.

What am I doing wrong.

Apparently they only appear from the cans on Thursdays, and even then its kinda rare.

How about you try and ask for one on the GTS or get FC to try and get someone with Ghost type safari to get a Shuppet. Cause Banette appear on thursdays in the trash cans and they are stilll rare to find.

I was trying last Thursday (Halloween) Also I put my 3DS Clock to Thursday after Thursday passed. Why is Banette rare then any Legendary lol.
