TEXT calculation and refund

I have work for Amazon in UK from April to October in 2022. After that I move to foreign country. However, until recently, my tax at that time is still NOT calculated!!! It is shown that "Your Income Tax has not been calculated yet for 6 April 2022 to 5 April 2023". This is really annoying! I use the tax calculator and it is shown that more than 2000 pounds can be refund! However, I can not even successfully contact HMRC through the online chat service. Please calculate the tax and give me the refund! THANK YOU!
