Horrible Company to Avoid - Book Hotels Directly

My husband booked rooms through this company thinking it was the hotel directly and at the end he saw that the reservation said it was nonrefundable so he called them directly to upgrade to the flexible option for more money. While still in the reservation and on the phone THEIR employee said he would walk my husband through changing (yes CHANGING) the reservation so that it can be modified if needed so we could come in a day earlier or later. THEIR employee said we could do so for an up charge fee. He never said we would be charged twice. We NEVER wanted to cancel the reservation! Their employee (yes recorded conversation exists that proves this) instructed my husband what to do online which basically instead of changing per our request for help cancelled the reservation then rebooked it immediately within a minute. We have the exact same dates reserved but this company has now charged us twice stating that we cancelled online so there would be no refund. This company is unethical and will not refund our money after multiple conversations with their horrible customer service department. Warning to others not to use this company and book directly with the hotel. We will be filing a dispute with our credit card company and I will make sure I do everything I can to help others from falling victim to this scam.
