Their customer service is totally non-existent…. Just not there. Honestly, not in any way. They ask you to email them if you have an issue, and so I did, a total of 20 times in two months and received not one response from either their ‘booking’ or ‘concierge’ sections. The telephone line is a complete waste of time as there’s not one real person available ever to talk to and always, irrespective of topic points you back towards the farcical email system. My vouchers arrived with no issue but not having a legitimate point of communication with your ‘travel agent’ is frankly worrying and I won’t do it again. I truly wish that I’d done sufficient due diligence as I wouldn’t have used OMG. I won’t ever use them again…….. Please rethink your options before using them.
