Bulk account support

I’ve called in multiple time to get the cable portion of our HOA bulk account set up. Even getting the Internet set up was a nightmare but I now I’ve called in three times and had a message chat one time. Despite providing the account number and address, I’ve been told there is no cable on the account or been promised a call back and gotten nothing. The HOA manager showed me a Xfinity bill showing that the HOA is paying for both cable and internet for the community so I know we have it. 

I’ve now spent over three hours just trying to get my cable set up. Please assist.
