I'm a long time lurker but haven't posted before however I'm in need of advice and hope you can help.
I've just booked rooms over the phone with a large, well known hotel chain for some employees. I needed to pay with the company credit card and so they said that they would send me a credit card authorisation form by email. I'm not a fan of this method and would have preferred to pay online or via phone but was told that this wasn't possible for a telephone booking.
The authorisation form duly arrived but when I opened the attachment, they have actually sent me the booking details including scanned passport and scanned credit card (front and back) of another guest as well as the email from the person in his company who made his booking.
I rang the hotel back immediately and spoke to a manager who was obviously shocked and asked me to delete the details. He said that they had been sent by someone in training. I said that under no circumstances was I happy to send my card details by email after this and all of a sudden the payment was able to be taken over the phone.
My question is, would you tell the other company who's employee and company data has been breached so that they can pursue this if they want to? The other company is large corporation and I have images of their employee's passport and their corporate credit card details. I will obviously delete these details after deciding what to do.
