My MCI lanline has been dead sins March 4th. I called repair took 25 minutes to get through on my cell phone. Here it is March 6th and my home lan line is still dead. No service tech has shown up to check outside box. and still no phone service. Will they still charge for the dates I had no service. I'm on my way to ATT
