Xfinity Blocking Fraud Alert Phone Calls

What happened? 2-3 months ago, the fraud alert calls from my bank were not blocked. Now they are blocked. I have to "allow" low spam risk robocalls for the fraud calls to get through. That lest way too many illegal robocalls thru. My banks fraud alerts use telephone number [Edited: Personal Information]. I have reported this number several times as a valid number being blocked. This needs to be fixed ASAP. I recently had my credit card compromised. Please fix this. Thank you.
