Amazon Digital Services Contact Number and Email Address

I purchased a Amazon fire seven from tesco at the end of July. Not being technically minded in order to get into the tablet it apeared that I had to give bank details I gave the long number accross the middle of the card, but not the three numbers on the back of the card My daughter saw games on the tablet that all said they were free I have since got a bank statement that amazon digital have taken well over £ 147 from my bank account. I would never allow my full bank details to be accessed and I do not know how it happened as I am unemployed. My benefit money went into my account and got swallowed up by the overdraft leaving me without money for food or money to pay bills I have had to go to a food bank for food to keep me going for the next three days. I have cancelled the card numberw awaiting a new one my overdraft is standing at £190 now So this as been making me ill with worry is there any way you can compensate me for this error, please advise Kind Regards Mr Robert A Jones .
