Credit One Bank added unauthorized charges to my account, no statement available online Las Vegas, Nevada

My statement in January showed 4 fraudulent unauthorized charges to my Credit One Visa card in the amount of $110. was told by person answering phone 877-825-3242, these would be removed as I had disputed them.  The following statement which I manage to find online, and later verified by a phone call to the "fraud" dept[888-362-0005} shows a balance due of $268 apx.  Again these were NOT charges that I made to this card, so it seems more charges have been placed against my card.  I know of nobody who would do this, and wonder if Credit One Bank itself is responsible for these fraud charges which I dispute.  There are many complaints listed online against Credit One Bank cards.  Unfortunately, I just now heard of them.  I was forced into bankruptcy in 2011, and trying hard to rebuild my credit rating, so I accepted the credit card offer from this "Bank".  Now it looks like this little lady of 80 has been scammed big time!
