Briggs Bus Lines

I have had nothing but problems with these buses/drivers. My 12 yr old son takes this line to school each day & almost everyday there is a problem either with the bus or the driver. There has been very cold weather & its unexcusable to leave children waiting endlessly past their pick-up time. My son has waited OVER one hour today, he has a new driver we are told. The bus finally shows, my son is gone now. Where is he?!!!! I will hold this company responsible! If I could get through via telephone I would not be emailing you now. We do pay for these lack of services believe it or not. OUTRAGEOUS!
