Expat Properties — Carnival plot near mopa airport

I purchased a plot carnival near mopa Airport from expat properties. Until now they have not registered the plot in my name nor are they refunding the amount paid until now.

Several emails have had no response and there is no phone number to contact.

How to get a resolution? If any one has managed to get in touch with expat group, please do share so that I can also get in touch with these people.
