think my sch scammed me...

i paid £55 to my sch to get my scripts back for lit/history/chem as i was 1 mark of a 9 in all and wanted to see if there was anything before i paid $50 per paper to be remarked - but i sent them an email and paid them 6 days ago and havent heard anything back and when i try to send them another email it says i cant cos the email is closed during the summer holiday...
