Lenovo — Cashback amount not yet initiated to bank even after 90 days

I've purchased Lenovo laptop on 12th FEB 2022 via converted EMI in ICICI bank debit card of tenure for 6 month. Cashback amount needs to be initiated to ICICI bank with sales invoice by Merchant-Lenovo after 90 days.

But this process not yet initiated from Lenovo team. They are simple saying that ICICI bank will credit cashback amount to my account. But ICICI customer care 4times clearly said that they have to initiate to transfer amount to ICICI bank then only bank will credit to my account.

This is very worst why they are giving cashback and not following properly to credit the amount to the product purchaser.

Note : Please find attached screen shot of sale invoice. Issue is not from ICICI bank, I need a valid response from Lenovo team.
