Update:  Xfinity rep made false promise, i was  not contacted yesterday as promised.  Note to Xfinity customer service - please instruct rep's not to provide a respond by time until they are 100% confident.

Called them again today since they never called me back ( surprise, surprise ).  Got passed to tech support and they were talking to me as if I did not know anything about my problem. Still trying to blame the modem MFG when I told them  I did factory reset and then had them reprovision the modem ( caused the 2.4, 5 ghz lights to start blinking when i had the modem in bridge mode).  Very unprofessional of them to do this to me, then I ask for supervisor finally. He says to hold while transferring me to his supervisor,  and all I hear is the line ringing.  Finally after several mins a person answered and was not the dude's supervisor.  That UNPROFFESIONAL TECH SUPPORT person needs to be placed into a customer relations class.   Anyways,  the nice lady who did answer suggested something the UNPROFESSIONAL TECH SUPPORT people did not ask to do:  did you try to disable bridge mode and then re-enable bridge mode now that you did factory reset followed up by reprovisioning.   I go, well did not think of that one because was so fustrated with my issue resolution.  Tried it and now only 2.4ghz light is blinking (wow progress after 3 weeks). Anyways this nice lady got me to her supervisor and hopefully the supervisor will follow through with my request because she has never had to handle a request to get a ticket opened with Xfinity IT dept.  We ended call on a good note for now awaiting for her call back on Monday to see.  

Hi Xinfinity,

I opened other call 3 days ago. Was promised by the tech i would be contacted 24-48 hours plus got bullied by Candice in your Phillipine call center when i explained the whole situatation, that really left very, very bad impression of that call center..... Well, no contact last night ( 48 hrs later ). Plus have not heard back from Rachelle ( fix group ) from last week as promised.  Plus went to local store here in , Macomb Xfinity store on monday April 5. Deneen [Edited: "Personal Information], store manager would see what she could do on her end. Sent email yesterday to her asking for update.  This has been going on for a month now and no resolution to the issue Xfinity has caused to the modem.  No more waiting on Xfinity's excuses, poor customer service, un-proffessional conduct on 3 way calls with Arris, being bullied by your call center reps and so on. I will be expecting a resolution to this by 5 pm, EST today, april 9, 2021, if not sooner.   BTW,  Is your CIO's email address:  [Edited: "Personal Information"] ?   also is your customer service VP email address:  [Edited: "Personal Information"] or [Edited: "Personal Information"]?

I tried to re-engage  using prior customer chat session by posting in it. So far no response for last couple of hours.  Great customer service response...
