Dear Sir/Madam,I am currently trying to book a visa appointment at the British Embassy in Beijing on your website. However, my preferred date is already not available and I need to come back next year. Is there any way that you can cancel this booking for me so that it will be possible to retry again later this year or early next year? Or if necessary, would you transfer my application onto another visa office in China?Please reply as soon as possible as we are due to arrive in UK shortly.Best regards,XXX
