In the last couple of times we have booked with HE. The first time everything was great. The second time we had to cancel due to the demise of Thomas Cook, tried to move the booking to March 2020 but couldn't as the same car park at Manchester Airport was not available. We had to cancel the booking and book again in different car park. We were refunded for the initial booking, all went well. This time our experience was not good. We cancelled on 15th March, the t&c's in place were free cancellation. We were advised it would be a voucher not a refund. We challenged this and was promised a cash refund on 25th March. On 17th April an email from HE went back on the cash refund and we were back to a voucher for a new booking. Not sure what worked, we emailed Matt Pack at HE and used Resolver. 5 days later we got a cash refund. To all those with unwanted vouchers do not give up. Use Resolver as they do respond.
