sash windows

I sent my strata manager an email a month ago requesting repairs to my windows and sliding doors which don't slide easily. It is nearly 2 months since I initiated the request and during this time they tell me they are trying to get quotes. Does it usually take that long to get a quote to fix several sash windows and sliding doors? Also when I also mentioned the locks on some of the windows were deteriorating, they said it wasn't common property. This is quite confusing as I thought that the locks were part of the window therefore should be common property. Is this assumption correct?

Thanks
