Mtn Terrible service

My husband upgraded online on Black Friday. I thought this was awesome because everything was so easy and simple and they deliver the phone to your door. He also got an confirmation email that says he upgraded to the discounted package and the handset he chose. Guess what?! No upgrade and no phone a month and a half later. We sent numerous email, made so many phone calls and also contacted them on Facebook. Mostly they promise to call back and it never happens or give another number to call which than refer me back to the previous one! One consultant said on Facebook that the upgrade is on hold because the handset is out of stock which is total nonsense because the handset is on promotion for January. They are useless, no one wants or know how to help. Never received more terrible service than this in my life. And this from a company we have been loyal to for more than twenty years.
