SBIcap Securities — Charges recovered but credits for dividends,cashbacks not given

SBIcap is sending e mails for demat charges debit and that if they don’t recover from bank or ledger they would levy DPC whereas they are retaining lots of our monies by way of dividends and cashback credit is being delayed since 21-8-21
I think this is not fair that they retain our money and one has to follow up constantly with them with no fruitful results at all.
They are working against public interests and action should be taken to stop such mal practices
