What a joke! Having pre-booked and paid for a one night stay on trip.com I turned up at 7.45pm at the Edgewater Hotel. Reception was shut and locked with the lights off. I called the phone number on the website repeatedly; it rang out with no answer. I sent an email to the Edgewater Hotel's email address; no response. After walking around the building and finding the whole thing locked, shut and empty, I was forced to give up and go to another hotel to pay again and check in. Now I will have to try and recover my money from these jokers, as I have paid for nothing but inconvenience.
Update: I received correspondence from the Edgewater Hotel claiming that they were unable to send a text message or email to me to inform me of where the key had been left because my details had not been passed on by the booking agent. I spoke to the booking agent, who agreed to arrange a cancellation with the Edgewater Hotel so I could receive a refund. However, when my booking agent called the Edgewater Hotel, their management claimed they had sent information to me and refused to offer a cancellation; in direct contradiction to reality and their correspondence with me.
Both the agent and the Edgewater Hotel are blaming each other, so it looks like it will be a long road trying to get a refund from either. Save yourself the trouble and book at another Devonport hotel; there are plenty of more reliable and reputable businesses.
