Redundancy entered wrong - am I being overtaxed?

Yes maybe that is the best option. He would be quite happy to do this but doesn't want to actually do the talking as he has anxiety issues but assume this would work if he gives his permission first. 

Thanks 

It is better to call at 08.00 when the call centre opens, as you will get through quicker.
At some other times of day you might not get through at all.

 Update-
Ex employer have admitted they got the P45 wrong and tax code wrong, so they have now reissued this showing the correct salary for April and May plus the PILON and corrected the leaving tax code to 1257L.

They say they spent ages on the phone to HMRC this week and the correct details are on the system now, but as far as I can see all the additions, subtractions and issues are still on there, the estimated income is still massively too high and the tax code is still a K...X code.
They say it's our responsibility to contact HMRC but two waits of over an hour today have me tearing my hair out. He also can't amend estimates income for original job online for some reason.

To actually work out what he should have been taxed can I just take his total income from the original and new jobs for the year and run it through a calculator with the 1257L applied to get the right amount of was there always going to be some sort of other tax code applied as he has changed jobs?

Tax codes are irrelevant once the tax year has finished.

You need to calculate the liability taking into account all relevant factors.

Things like Marriage Allowance, other income such as State Pension, tax owed from an earlier year etc.

As it's shortly going to be the end of the tax year. All will come out in the wash. Given a little time.
