No feedback and delay in claim.

I logged a claim with RenewTech in January and I am not getting any feedback. The initial claim that was processed was incorrect and the person who was handling my claim (Phillipine) called me and said she would cancelled the previously authorised claim and send the new quotations and they would approve that. I have not had any response ever since. I keep emailing and there is no response to my emails. I called a number of times but I keep getting transferred to the wrong departments or being put on hold for long periods of time. I am entitled to a claim every 90 days which I forfeit if not claimed, and the end of January was the end of another 90 days. Can this please be rectified and my claim authorised as the 90 days that passed in January was because of a delay from you guys and not myself.
