I have one case here.
This number I just registered just to buy property, so I was attempted to purchase one property from Sunway Properties in Bukit Jalil and my loan unable to approve due to personal reasons.

Not long after that this number start receiving spam text messages from different property agents and even calling me.

I am very disappointed with this Sunway Property because I only let them know my number just for the sake of buying property and I don't know should I proceed to file a complain (i have deleted those messages and blocked those numbers).

I know it is a common practice that property agents will sell my data but didn't know even Sunway too.
