Samal Island Warnings Or Dangers

Last week, my friends and I went to Penaplata, Samal and stayed at Fernandez Resort. A guy in the resort recommended Jay to drive us to Maxima Resort. At first, he was accomodating and offering us help like accompanying us to buy pomelo and coconut, and he was even willing to take our pictures.
When we asked how much per piece of a coconut, he said Php 10.00 and he would be able to deliver the same within the day. However, when it was about 5pm I asked about the coconuts, he said he will deliver it early in the morning and said that we must pay first before delivery. we paid Php 80.00 for 8 coconuts. after our dinner, he told us that the coconut will cost us Php 15.00 each contrary to the price which he previously stated and demands Php 40.00 for his transportation. We were hesitant and would like to demand our money back but he told us that he gave it to the seller already.
Since we do not trust him anymore, we lessened the quantity of the coconuts and just ordered 3 -equivalent to the value of what we gave him plus his transpo. We waited until we checked out of the resort and we have not seen him or heard of him. I know Php 80.00 is a small amount for Manilenyos but DISHONESTY of locals such as Jay might affect the resort's reputation and even penaplata's. kaya guys beware. he will gain your trust. he is a smooth talker. DO NOT TRUST this guy.
