Angel Broking — History of purchase of shares not updated in the shares transferred from another DP

Address:

G-1, Ackruti Trade Center, Road No. 7, MIDC, Andheri (E), Mumbai - 400 093.

Dear Sir,
I applied for closure of account to Kotak Securities and instructed to transfer the shares to angel broking. The Kotak Securities transferred the shares from Kotak Securities to Angel broking on 11/01/2021 at the prevailing rate of the day.
The total invested amount in individual shares has increased from the actual amount initially invested. In some, a particular case investment amount is being shown as zero.
I tried to appraise the situation to the executive at Angel Broking office at Jaipur but they say that nothing can be done as we do not have the previous record with us.
When I contact Kotak Securities it is said that the account has been closed and it is up to angel broking to complete the details. It is difficult to provide the details of the source of the escalated amount to income tax authorities.
Kindly provide a solution to this uncalled for situation and oblige.
