Good thing we can't see your face...................
Anyway, that's definitely a lager yeast. http://www.fermentis.fr/FO/pdf/HB/EN..._W-3470_HB.pdf
It sounds like 12 C (53 degrees) will be impossible for you. You can try two alternatives. One is to go buy some ale yeast. That's what I'd do. Buy some ale yeast and ferment it as close to 68 degrees as you can. It won't be an actual maibock (which is a lager) but it will be a tasty beer and trouble free.
If you want to proceed with this a lager, you could try putting a bin with cold water in your basement and some ice bottles/frozen water bottles and pur your fermenter in it and try to keep it at lager temperatures for 2 weeks or so. It's not easy, but it's possible.
After the fermentation is over, you can rack the beer to a carboy and then put it in the fridge with either yeast.
