Die Dam Resort - No customer service

We wanted to go for a weekend away to Die Dam Resort. We have emailed them, contacted them on their landline and cellphone provided. It is now 3 weeks, no feedback from the email, no one is answering the landline and the cellphone is always off. We are very dissapointed. We wanted to go and experience the beautiful place, but I dont think that place will ever see me. Sorry to say.
