Tax refund not happening

I completed my self-assessment on 11th November 2022. On 14th November, I checked my account and the return had been processed. That day, I requested a refund into my bank account. The response said I'd probably have the refund within 2 weeks but it might take up to 4. Nothing has happened. I have repeated the request 4 or 5 times, and each time I get the same message saying I'll have to refund within 2 weeks, but I haven't got anything, and each time I check my account online, the money is still showing there. Why is this not happening? What do I need to do to get my refund?

Could I get a response to this, please? Even if just to say it'll take months. All I kept being told - for more than 3 months now - is it'll be in my account within 2 weeks, over and over again.

Hi
If the refund isnt showing as pending, you will need to contact our helpline to check if there is an issue stopping the refund being issued.
