This week we have had 2 notices delivered re "underpaid revenue" on christmas cards, 1 for 9p the other for 19p. For both we were charged £1 cost, WTF, When i asked why they said that a LARGE 1st class stamp should have been used as they were a larger than normal xmas card?
I also had this in april when i sent my father a birthday card with a left over stamp from xmas . ( clearly a xmas stamp as had xmas trees on ) he also got charged which i never heard the last of
AIBU, if i paid for a stamp then surely i paid to send a letter regardless of when i use it ?
