I know your response to this was probably the same as mine, which is "This makes no sense." I would be willing to bet that there was no attorney involved and certainly not present and that no attorney revised her Will. You can't cancel a deed "by phone". It is correct that it takes several weeks for deed to come back from the county clerk after it was filed. But normally there would be a copy of it available immediately. Is she moving to a nursing home or assisted living? I don't understand why she needed to sell. Someone needs to get a lawyer in Paris to look at this immediately. If she was taken advantage of it may be possible to undo the sale but she has to move quickly.
