No Response for local AT&T Rep

I've been emailing and calling my local Rhode Island rep since March 3rd.  I have many issues on my account I need fixed and he's completely unresponsive.

Tech support has screwed up my account 3 times now.  This is why we have a local rep to deal with multi line issues.

We have 13 lines, been with AT&T wireless for 20 years.  I've been the mind of "It'll take more of an effort to move to another carrier"...but I'm here...searching for answers on a support forum.  Hopefully someone can offer some assistance.

My current unresponsive Rep.
