Sprint MPLS monitoring sinks to new low levels.

One of my clients has 11 sites connected to an MPLS network provided by Sprint and part of that service is proactive monitoring for outages. For the past 3 months Sprint have been unable to contact me when an outage occurs as they cannot update their contact information correctly and when they do contact me (or I call into their support center) they fail to meet their SLA's of 1 hour on ANY of the many outages we've had.
The call I received today is the worst I've had. Two days ago one of the lines was disconnected (and Sprint notified). 48 hours later I receive my first phone call from Sprint telling me that there is an outage. 48 hours for a proactive monitor?????? The weird thing is that the ticket stats show they have advised me of the outage but yet again they called the wrong number. I have no idea why they are monitoring a disconnected line but 48 hours to let me know is a VERY slow response time.
