When vehicles are not driven over extended periods, rust would form on the grooves of the pulleys. The rust would wear the belt very fast unless they are removed and the grooves smoothened out.
Check if the grooves are uneven with pocked marks on the grooved surfaces. If yes, unless the pullies grooves are polished or the pullies replaced, if not, any new belt would not last.
