My wife and I ordered and paid for a double entry visa to enter mainland China in Spring 2016. The visas printed into our passports, as supplied by the Chinese consulate in London, were posted to our home by Visa HQ shortly before leaving the UK for China. Unfortunately it did not cover the dates we needed to enter mainland China twice. This was not obvious to my wife and I because of the Chinese script used in the wording of the visas. However, having paid to use the services of the 'experts' at Visa HQ we felt secure that we had obtained what we need and what we paid for. However when we arrived by train from Hong Kong in Beijing for our second entry we were refused entry because the visas had already expired and were returned to the airport and forced to fly back to Hong Kong airport. At the airport we were able to purchase emergency visa and we able to fly back to Beijing. We incurred considerable anxiety and distress from our experience; lost two days of our holiday; spent an uncomfortable night at Hong Kong airport; we forced to pay around £2000 for flights between Beijing and Hong Kong and return; we were forced to purchase emergency visas at Hong Kong airport. On our return to the UK we complained to Visa HQ and sought recompense . The response was basically that it was our fault for not checking the visas before departing the UK. We suggested that the visas were opaque to us because of the language difference and that we had expected Visa HQ to check them before posting them to us, as part of the 'expert' service we had paid for. We claimed that the service supplied to us had not been fit for purpose. We subsequently received a phone call from a lady at the Visa HQ. She sympathised with us but said that the mistake lay with the Chinese consulate in London and promised to raise this with them. To date we have had no further contact from Visa HQ despite sending a chasing email some time ago.
