The worst service ever

I received an sms on Friday saying I'd be getting my package but I never did, called at about 2pm and was told the driver said they'd be there an hour and half later. My package never arrived and when I called again their line was off, found out they don't deliver on weekends and waited for Monday (today). I still haven't received my package, I've been calling their customer care line and was put on hold for more than 45 minutes, I emailed them still no response even though the automated reply says they'll contact me within 45 minutes. So I basically cannot get ahold of anyone to help me and the tracking site hasn't been updated since friday
