Icici Direct — Amount not credited

Yesterday I added 400/- through icicidirect app via gpay. Transactions was successful and received confirmation message from my bank.
But it is not added in my ICICI direct account. I called customer care ( which is not toll free ) number of icicidirect and they confirmed the acceptance of amount and told me that it would be reflected in 4 hours. Today i checked the account but it is still not credited.
I added the to run a good deal of stock purchase and due to this cheating i lost a good deal as well as my money.
Please look into this matter and take strong action.
