Uti Infrastructure Technology & Services Limited [Utiitsl] — PAN Change Request is Withheld

I have raised a request (U-Q[protected] with UTIITSL on 23 Jan 2020. The request is still in hold saying "Mismatch in Father Name". But I have already provided the required doc on 25 Jan 2020 and I got a response from them saying that it is under process. Since there was no further response, I followed up in June 2020. Then they are asking for the same details which I have already provided in Jan 2020. So as part of that I provided the details again. Still I am getting the same response asking for the same details. I had followed up with them nay times and given below are the support request numbers :

605008, 939963, 159845, 604143 and 320117.

At the end their response is that they need two proofs for DOB. Also that is to be attached in the mail even though it is the request I submitted. To get this response I had to follow up with them many times.

I would like to complain about this irresponsible act from UTI. If this is the case they should have informed it in the response for the mail I sent on 25 Jan 2020 itself, instead of taking this much time and follow up from customers end.
