DMCI Cypress Towers — roof leak

I was notified by the PMO at CYPRESS TOWERS that most residents with roof leak have not filed a formal complain to the management. If you have a roof leak, please file a written, formal grievance, specify that you need to get a concrete corrective action and a reasonable time frame when the problem could be resolved. A complain is just FYI to DMCI. A grievance means you expect something must be done in certain period of time. Also please do not forget to include a good contact number so that they cannot say that they could not reach you. They need to update you of any development.
The best thing to do is write it in black and white and have it notarized. Send it via registered mail. Make a copy for your your file before sending it. Do this if you care about your investment. Also pls contact me thru facebook--Tribu JSC. We need all this just in case we request 2 Senators from Taguig to help us.
