Transfer from Comcast Business to Xfinity residential

We need help from someone knowledgeable that is able to help transition from Comcast business to Xfinity residential. We have been told repeatedly that it is no problem; however, every time we contact Comcast business they refer us to Xfinity residential for the transfer. Xfinity residential then says their hands are tied until the business account is closed and the home is transferred to residential. I have read email threads that state that can take an additional 1 to 3 months. We’ve already been trying to get this accomplished for over a month. A supervisor on the residential side submitted a request for transfer about 2-weeks ago, but it still hasn’t processed. We’ve completed the discontinuation of services form, and have spoken to numerous representatives on both the business and residential sides. Although everyone concurs that it is possible, no one is able to help. I am not sure why this is so difficult, so need to speak with someone who is able to assist to ensure that we do not have a lapse in service.
