The reviewer booked 5 nights on our internet site at our clearly shown rates for February high season. He stayed the first night in the cottage on the sand. Next day he said it was too close to the sea, so he moved back to a larger unit which was $35 a night +10% tax more.
He did not pay the full $35 for the change.
After he left he saw our low season rates on the internet and asked for a refund for the amount between the high season rates and the low season rates with a threat to report fraud to TripAdvisor if we did not succumb.

I'm showing the email correspondence (with only minor exclusions of irrelevant sections).

The guest had no complaints when he was here and it is worth noting that his ratings bear no relation to the previous 7 reviews regarding' location' where we received 34 out ot a possible 35
and 'value' (33 out of 35),

I show here the emails (leaving out the identification of the guest as is required).

"So one night at cozy $130+10%= $143.00 plus four nights in apartment (considering the maximum tariff for a garden view ) $150 +10% per 4= $ 660.00 for total amount of $ 806.00 not $1,209.00 that I payed ( whit this amount a lot of ‘ all inclusive’ resort in negril are available ).At the end I would prefer that your organization will reimburse me the difference of $406.00 instead of thinking in a Jamaican defraud .I am waiting it before explain my opinion on trip advisor ."

My reply:
"Dear ----.
You must know that hotel rates in most countries go up or down according to the season.

In Jamaica rates are lowest when it is summer in the USA, Canada and Europe. Rates are highest when it is winter in Italy, Europe and North America where most of the guests come from because the climate in Jamaica is at its best.

The main busy season in Negril is from Christmas to the end of February. For hotels that seek the university students on their Spring break March may be busy. So it is to be expected that a rate of $130 + $13 tax = $143 would apply only to the low season, and that the high season rate would be 50% to 100% higher. Our website shows very clearly that only our low season rate is $130 + $13 tax.

Until this week we did not have the facilities to show rates in US$ when guests made reservations on the website. However, we did show on another page our standard high and low season rates in US$, which have remained almost unchanged since the recession started about 4 years ago, although inflation has continued.

When I did conversions between £ and US$ I used a rate of 1.55 to 1, which has been close to the rate quoted by money changers. You made a booking for 5 nights at £135 + 10% tax a night for a total of £743. You paid a deposit of £216. This was your choice, booked from our website. The rate is very competitive .

When visitors arrive at Firefly new transactions are often done in US$.

For four of your 5 nights you asked for a penthouse suite which has a rate about US$35 + tax higher than the room originally booked. So if I convert £743 to US$ at 1.55 to 1the amount is $1114. Adding four days at $35+10% is another $154. So your total is $1268. Mrs. Dell tells me that you paid only $1210. This agrees with the figure ($1209) that you told me you paid. You will therefore understand that we should have collected a further $58. If you wish to return in late April or May or June when the climate is still nice you will of course get the low season rate and a discount that we offer to returning guests. And we would be delighted to see you again. If you have any other items to discuss please don't hesitate to contact me.
