I'm sorry to hear that the address details are still showing incorrectly. @DavidM is out of the office at the moment but I'll get him to get back in touch with you on Monday.
Sorry for the delay in getting back to you. @DavidM has been out of the office sick all week. I sent this off to Openreach and checking your address it looks to have been corrected. Give it a try again and let me know how you get on?
