Taxes and NI deducted on my payslip not showing on HMRC app

Good morning,i downloaded HMRC app and i discovered that my current employer was omitted.I called HMRC and they created my current employer,asked me to logout of HMRC app and login back after a few hours.The problem am having now is that on HMRC app it’s showing i haven’t received payment from my current employer.I contacted my employer and they confirmed that they have been paying taxes and NI on my behalf.Said the issue is from HMRC,told me they can’t do anything from there end..I need an advice regarding this,I have my payslip and P60 showing the amount of taxes and NI that have paid

Hi,
Please contact the helpline who will be able to check your tax records and advise you of what action you need to take to get your pay and tax details added to your tax records:
Income Tax: general enquiries
Thank you.

Have contacted the helpline,I was told to contact my employer.My employer confirmed that nothing they can do from their end,that everything is correct from there end.My employer advised me to contact HMRC back,I’m serious frustrated.
