centurylink brightspeed are not activating my emails or billing account Nationwide

as of 10-03-2022 centurylink sold various accounts to brightspeed and promissed that there would not be any issues with the transfer and it wouls be seamless which it has not been by any means as most email domain names were not activated on the new servers so it was as if they were not transfered and they said just change the passwords but this was not acepted by the servers so still not able to access any domains and even not able to access the billing account on the web pages. my prob lems went from bad to worse once i contacted the technical help lines where i was answered byt people from onther country with almost uninteligable accents and a total lack of caring for the problems or any technical understanding of the workings of the ISP's systems whilst being unable to help with the problems the would transfer me to another person that was not the and the system afer an hour plus holding on was then disconnected  and or hung up on and whilst this was going on the HQ of the company was moved to a new address and the phonlines were not maned and the snwering service said leave a message and we will call back but they never did and a message from one number stted that they only work monday to friday 8am till 5 pm this has to be the worst company exoerience ever.
