I contacted True Blue Dive in the beginning of December 2012 and explained that the earliest time I could do my diving course was in February and I had already specific date in mind... They said it wouldn't be a problem and after I purchase the deal (this was through one of the deal companies) , to send them email or call them just to confirm and tell them the date. So I bought the deal and called them and send the email.... But they told me to go through their booking system on their website. Unfortunately their calendar was showing only December, January, not the February.
Right from the beginning I sent close to 15 emails requesting to be contacted and confirmed that dates I wanted could have been booked. (I was overseas at the time and wasn't always able to call them due to the time difference). I was ignored until finally someone replied to me. By this time February calendar came up but was showing that all dates (every single day) in February was booked and not available any more.
And I also wasn't able to contact them at all, neither by email or phone call.
Thankfully I was refunded the amount I paid for voucher by the company I bought it through.
I wouldn't recommend True Blue Dive as their customer service is beyond any comment that could describe the awful experience.
