The point is that account details were NEVER given to Rewards Now, only to Credit Expert on their supposedly 'safe' system. Credit Expert's conduct towards me makes their accolade as 'business of the year' ring distinctly hollow in my ears (unless the prefix 'Pontius Pilate' was somehow missed off), and I certainly will not patronise them and fund their rudeness again.
Incidentally, since updating I have been approached by someone else who had similar experiences with Rewards Now, but whose credit card company agreed to refund after being told that their customer had never signed up for this nonsense. She also found the telephone number given for this supposedly legit company given is out of order.
Avoid Rewards Now like the plague.
