He was fine said he would have a chat but I asked would you hel if this lot won't canx they both said yes.. life goes on waiting for bed rang them euro parking to explain what had happened not interested use the appeal so I did only to find they are the appeal .rejected rang dreams nothing to do with us not our property so it's a set up ?
