This sucks

Grandma got scammed again. The same vacuum cleaner people that talked her into buying an expensive machine a few years ago have struck again. They came to "maintain" the machine as she had bought an extended warranty and left with her Visa authorization for over $1100.00. Crooks! They left phony contact numbers and not much else to go on. The woman is 84 years old, can not walk and only has one room in her house with carpet. My family is outraged! I hope these people get what they deserve.
