Previous employer not giving me UAN no - unable to login to PF member portal?

Hello Sirs, I don't have UAN and PF no where I had worked for a few days and left a few months back. As now I'll join another company I need that UAN, but my previous employer is not giving me that.
I tried to get it from member portal and below error is coming - Entered information does not match with any member. Screenshot is attached. Please help me. I have given all possible mobile nos still its showing this error.

Sir, The screenshot of the page is attached. Please tell me what should I do. They had told me that they have linked my aadhaar with my uan, so I can get it this way, but yet I'm unable to find it.
Please help.

It is compulsory to every employer to provide UAN number to all the employees, If your employer is not giving please write a letter to PF Commissioner cc to Enforcement officer they will help you.

I don't see a reason for an employer not to share this piece of information with employee. Try reminding them again, before taking extreme actions.

Dear Anamika, you have stated that you have worked only for few days? for how many days you have worked? Has salary been paid to you with PF Deduction? perhaps Employer would not have remitted PF Contribution for few days of work.Only after creation of UAN/PF Member ID- Aadhaar Number can be seeded.Find out from your Employer factual position

Sir, worked for only 12 days, yes salary paid after pf deduction, but in pay slip UAN or PF Member ID is not mentioned.
However since they have deducted PF, they must have deposited it somewhere and as per them they had linked my Aadhar with it. Still unable to get it using the EPFO portal.

Dear All,
From employer point of view.
1) resigned employee has to submit all NOC from the market (Sales Employee) or Dept (Office employee)
2) resigned employee has to submit all company properties (ID card, Files, Laptop with charger, Mobile with charger & accessories, Car with keys).
3) Resigned employee must pay notice dues.
If all above is done then i dont see any reason as to why employer should deny UAN.
