Asurion ,purchased at Musician's Friend, Musician Friend broken bridge on cello, has had for over 3 months and still not fixed Nashville Tennessee

Purchased a cello from Musician Friend in July 2015, ordered a hard case to protect it since it was going to a high school. Case did not get here until Jan 2016.  In December the bridge on the cello broke due to being bumped.  I had purcahsed the 3 year extended warranty from Musician's Friend.  They told me to contact Asurion.  Shipped cello to their repair shop on Jan 29, got signed tracking confirmation from UPS.  I called twice to check on cello and they had not done the repairs, asked for manager to call me back, they said it would be 24 hours, two weeks later a person called back on April 15 stating the cello would be repaired on April 16 and shipped priority to me and I would have it no later than the end of next week, which would have been April 22.  Today is May 4th and they don't have a clue where cello is or if it is even repaired, said someone would call me back in 2-3 days.  I told her not acceptable asked for manager.  Manager said all she could do is send this to the resolution department and they would call me back in 2-3 days.  This company is a freaking joke!!!  Do Not Purchase an Extended Warranty from them.  My daughter has had to borrow a school cello this entire semester and is fixing to leave for Orchestra camp with no cello.  Wondering if I will ever get my cello back and if I do what kind of condition is it going to be in?!?!?!?!?!
