Sigma's terrible customer service

We had a leaking roof and ceiling in our unit since the end of Feb. The leaking roof and ceiling in our unit was brought to the attention of the managing agent SIGMA at the end of February to date the roof is still leaking and no repairs have even started. Our bedroom ceiling has extensive water damage that is only getting worse over the past 2 months as it continues to rain. When it rains we have to put towels on our bed and furniture and buckets to collect water to prevent further damage, the towels and bucket have to be continuously drained or replaced every hour or 2 during heavy rains. We have had numerous sleepless nights and are unable to work during the day when it is raining as we have to empty buckets and drain towels!! We are unable to leave our house unattended in case it starts raining, we have not been able to go on holiday or stay away from home for hours! HOW CAN WE BE EXPECTED TO LIVE LIKE THIS FOR 2 MONTHS?!!

Over the past 2 months when we follow up with the progress on getting the roof repaired the estate manager appointed by Sigma provides feedback that they discussing with the trustees to get the repairs approved. Why is it taking 2 months to get quotes and get this approved? I just cannot understand why there is such a lack of urgency to an emergency situation?

The turn around time to get a reply is shocking. I requested a form for an additional access remote on 8th March, 2 days later I received a reply from the estate manager saying they are waiting for the forms and he will send it once he receives it. I have followed up since then and I have still not received the forms. Does it take 7 weeks to develop a new form for access?
