Query: complaint

when purchased goods I was charged postage and packing "when goods were delivered you had charged an extra 12.67 this I was not made aware of"I am not satisfied with this extra charge I have emailed you many times to resolve this over charge but you have chosen to ignore me,I will not be purchasing any more goods from Amazon please close my account now" its a bit late for excuses""""I feel I have been conned.
