Hi, just to make people aware... I noticed yesterday that i could no longer log into my Quidco account, so i checked my details on my phone which is always signed in, i found my email address had been changed to someone else's without my permission. Then i noticed a payment had been made via an android device (i dont own an android device) in Nov 17 using the amazon gift certificate pay out (presumably sent to the unknown email address). I suspect i wont get my money back (not a massive amount) however i hope this helps to make people aware and advise people to continually pay out your cashback to prevent any large sums being stolen. I have sent an email to Quidco support and i await their reply.
