No easy answer to this question. A cases take priority over C cases, but you must keep in mind that different applications are supported by different call centers and different agents so it is possible that an A case could take longer due to the nature and severity of the problem, the backlog of cases, etc.
This is kind of like asking why I can get an oil change done in 15 minutes but a driveability can take hours or days, even though to the consumer it looks like both jobs go into the same shop...different techs, different skills, different baklog of issues, different complexity of the problem.
Now, with that said, we would be happy to look at your specific cases to make sure we have not missed the mark or not handled as well as we could have. Being that our profiles no longer list our contact info on this site...if you want me or the ADP team to do a bit more research on this, can you reach out to me at my email address (
matt_parsons@adp.com) and let me know how to contact you and our Customer Care Manager said he would be happy to get engaged in this.
