Dishonesty

The team you meet with is great and lovely people. The people I spoke to on the phone were polite. However, my wife’s suit leaked all over her and we had to return to town wet. Also, due to a misunderstanding about age, 2 members of our group weren’t able to go. No big deal, the staff the day before told me that they would alter the group number. Then the day off and after the event, they emailed me and changed their mind and wouldn’t refund me, claiming their policy won’t allow it. The truth, they blamed Viator, then Viator blamed them. It’s not worth fighting but the dishonesty bothers me. Tell me you won’t refund me before I come, don’t hide behind an email and a policy. They could have refunded us if they wanted. This was my second time, there is 30-40 people in a group that comes every other year that I am a part of and they will not be using dive in the future. I am not saying don’t use them, I am giving an honest review.
