Identity theft/fraud exposure

On booking, my credit card details were requested ,card number including the 3 digits on the back to secure. Two options of paying, via credit card or EFT. I chose EFT supplied copy of POP on arrival. An extremely detailed form had to be filled in with all my personal details. A copy of my ID-AND- a photocopy of my credit card front and back was required! They insisted that I sign a blank swiped credit card voucher for safe keeping in case of damages. I have recently suffered Credit Card fraud. The procedure did not sit well with me, I didn't argue as we didn't have time. I felt very uneasy due to this incident. Prior to check out, I requested the return of the documents. The Manager at the front desk assured me that it would be no problem, he would tear it up in front of me. On booking out I requested that the room was checked and that they return the documents to me. The manager left me standing in reception for about 20mins whilst he searched for the signed credit card slip and the photocopy thereof. To no avail.Reasons varied for the necessity of the documents - also conflicting reasons. I left with an extremely bad gut feeling and cancelled the card to protect myself
