Outages and credit limit

How can I speak with a live person (not Xfinity Assistant) regarding billing credits for constant outages? Over the last 3 months we've experienced 15 outages, nearly all of which were during normal business hours. From 12/11 through 1/10, there were a total of 8 outages (more than 25% of the month!), including 1 which was not fixed until the following day, so really we had 9 days of impacted service - all weekdays during working hours. Since my husband and I both work from home, you can see how this might be problematic.

I followed the automated system for requesting outage credits but received a paltry 2 $5 credits (so $10 total) before I was informed that I had reached the maximum number of credits. Yet there seems to be no maximum limit on the unplanned outages we experience. Please advise, thank you!
