Kind of doubtful that UMLAND would play such dirty tricks. However if they were (which I wish they are not) i suppose their strategy was firstly to get an agent to get bookings for 150 units and note that the contract lapse clause is somewhere in June (correct me if I am wrong), which is calculated with buffer allocated to the maximum delay to the GE in malaysia.
If BN wins GE, then let the contract lapse as property prices will continue to boom in Iskandar, no harm to UMLAND 's image or reputation and deposit were taken by NSG. During that time, I noted that UMLAND whether it is JB or KL office, did not seem to acknowledge NSG taking deposit for Matex. they keep saying that it is not launched yet, so I may just register expression of interest.
If they did this, it is purely greed motivated. shame!!
