Can't make outgoing calls, Outgoing calls hang up on customer, No response to first post

Hello, I made a post back in early July to which I never received a response and it appears to have gone into a black hole. I have a call into customer support to which I also have not received a resolution (from WEEKS ago). I cannot make outgoing calls from within the app. I am not in the office due to Covid so I cannot properly manage my business calls due to the poor functions in the Comcast voice app. For some reason Xfinity has a great voice app but Comcast business' is terrible. Why? 1)  I am unable to make any outgoing calls within the app therefore I have to make business calls separately by writing down the number and then make a call from my cell phone by blocking the number - extremely ineeficient and inconvenient and very unprofessional 2) When I attempt to make outgoing calls, it still calls the person later with me not on the phone and hangs up on them! This IS A BUSINESS and COMCAST is killing it with their low class, cheap app. 3) Why can't the Comcast business phone app allow us to tell when a business call is coming in PRIOR to having to answer all incoming phone calls? This is ridiculous and I don't see why on earth anyone would develop or keep an app this way unless they just don't give two about their customers. I've seen so many comments on this online and, additionally, customer service people at Comcast have told me that it's been an issue for a long time and not to expect Comcast to do anything about it because they don't want to change it- regardless of how many unhappy customers they have 4) I made this post weeks ago and it has gone unresponded to and when I search for it it says I have 2 comments but only shows me one. So where has it gone and why haven't I had a response?  HELP! Customer service won't get back to me on this issue in any way shape or form. They responded immediately after my first call about it via email (wihtout so much as a phone call) and responded incorrectly as they misunderstood the issue!
