I noticed that complete savings had taken £15 from my account . When i looked on the net to find out who this body was , Neither myself nor my wife recall ever having heard of them . I sent them an email asking who signed up and through which retailer etc . I also gave my bank account number and sort code . They responded with (we could not find your account and could i send them my account details so that they might assist ) . I responded with the fact that I had already sent them my details and suggested it was strange that they could not find my account , but seemed to be able to find my bank account to relieve me of monies . Having read an article on WHICH , which stated that complete savings claimed that they sent all new clients 5 emails during the first month to verify membership https://www.which.co.uk/news/2017/10/beware-costly-online-cashback-schemes/. I checked both my and my wife's emails for any communication re the account and there was none whatsoever (liars). have emailed them several times recently but got no response
