OMG where do i begin its still a total nightmere for me nothing has ever been sorted

Ok so i was refered by a friend to have some photos taken and hair and make up on the day i thought great
the deal was to pay five pounds over the phone and get hair and make up done and some photos these photos we were under no obligation to buy atall!!
i checked before and when we arrived.

So the day went well and then we had to go into the viewing room where we viewed are very nice pictures and then came the prices OMG £75 FOR 1 PHOTOGRAPH
we explained that we didnt have enough on us and then they started throwing deals at us like ok take nine pics pay £75 deposit doay and £22 per month for 9 months and we can leave with the photos today
Although i dont think they was getting it we hadent brought any money with us so we agreed to sign all paperwork and phone later that day with the £75 if we still wanted the pictures the lady said that was fine but only on the condition that she would post our photos once we had called back with the deposit which was understandable and we left.
WE NEVER CALLED BACK!
WE WAS UNDER NO OBLIGATION TO BUY
WE NEVER RECIEVED ANY PHOTOS

BUT £300 WAS DEBITED FROM MY CARD !!!

WHAT A THEIVING BUNCH OF ********* I dont know what to do or who can help me !!!
