my name is leanne plant i want to know why i have had £14.95 taken out of my account when i have never heard of rewardsnow.co.uk i want the money back please

rewardsnow took £14.95 out of my account did not sign up did not go on there site did not know about them they have stole of me want my money back scammers ripped me off grrr

I went to check myt credit rating last year July with HIGHCREDITSCORE I noticed that I was also being charged £29.95 and another set of charges of £29.95 from REWARDSNOW then later I noticed another set of charges of £6.99 by CREDITEXPERT I wondered why I had been charged with these amounts as I signed up for a FREE TRIAL giving my debit card as reference and since then have paid a considerable amount of money.
I cancelled the accounts with both HIGHCREDITSCORE/CREDITEXPERT but did not think of REWRDSNOW having just seen these amounts going out of my account rang my Bank to cancell this account and have changed my debit card.
How do I go about getting my money back ?
Yours faithfully
Anthony Perry
