I believe there are many property pro here and experienced professional that can answer my question.
I have some problem with the developer with incomplete defect rectification after I sent a final notice giving them 30 days to rectify before I rectify them using my own contractor (as stipulated in the SPA). The deadline ended on 18th October 2020, and I engaged a contractor to rectify the defect. The rectification process is still in progress, and today, I received this letter.


My question is, after I complete the rectification, should I go back to the developer and claim the costs, or should I go direct to tribunal since the developer now formally refuse to acknowledge that the problem persists?
Here is the summarize timeline:
10th July 2020 – received keys
14th July 2020 – sent out defect rectification
15th Aug to 14th Sept 2020 – extend, extend, extend, extend
17th Sept 2020 – Sent out notice to rectify on my own according to my rights stipulated in SPA (30 days notice)
9th October 2020 – I follow up after I see nothing been done, said in progress.
14th October 2020 – Request for 14 days extension. I said If you resolve the crack issue, I will consider, otherwise, no.
18th October 2020, 6.30pm – I went to check the crack, nothing been done.
19th October 2020, Morning – Crack was hid with simple patch, patch mark was visible.
19th October 2020, Afternoon – Crack reappear after the cheapo patch dried.
19th October 2020, Afternoon – I inform the developer, no more extension. Call contractor to measure window frame.
27th October 2020 – Developer contacted me to install new window frame, I said, no, I already ordered myself
30th October 2020 – Developer sent letter said everything has been completed. Consider the matter resolved.
Here is some excerpt from the correspondence:
