I have been asked to digitally sign an agreement to purchase a new IPhone 11 pro max through the Xfinity website and for the link between the site and I. I am unable to take this action for a lack of knowledge in how to! Will you help me? Please. A delivery is due to arrive this evening and I have been unable to find a way. I believe that we opened over 50 browsers and I am so embarrassed to say that I was uneducated about the proper way of it.
