Bad customer service

submitted a claim on 31/01/2023 with my employer was acknowledged as received. I have followed up on several occasions by email and requested a progress report but to no avail. I called their Call Centre yesterday afternoon and was told that I would receive a call back .since promised I will get back my payout on the 28 March 2023 until now nothing received.Their service levels are slipping - getting worse every day!

Your help will be highly appreciated.
