Unreliable service

 I run a restaurant that depends on phone service and this is third time in  a month that  we have lost service . The  first time it went down   with no ability to forward to cell phone on June 6 - 7 .  Which at the time callers were told that the phone number was not in service .. I don't even know how many callers that called and think we are out of business. We were told this is  a rare occurrence and that you fixed the problem . Well last Friday our busiest day it went down again and I received some calls on my cell phone  but was unable to handle all three lines and lost numerous customers and the ones that I was able to  talk to I could not process cards due to the Internet being down also. .       I opened my bill today thinking there would be at least a  credit for the horrible  service instead Comcast raised my bill $20 .         Our business is out literally thousands for those days but the worst part is the customers who threw our menu out thinking we were out of business  due to that stupid message saying " We sorry the number you have dialed is no longer in service".  

Has anyone  received a credit or even an apology for these business killing outages ?
