State Bank Of India [SBI] — does not update my ledger balance

Address:

Kandi Kali bari Road, Murshidabad, West Bengal

I, kajal ghosh, a regular customer of sbi. My account number is [protected]. On 01/08/2019 the amazon has issued a refund of rs 364 (Three hundred sixty four only) via the authorization code (Refund reference number) for the transaction is 783585. But still today the the amount is not added to my accont. I placed the matter under their nose for several times. But no measures have been taken yet. I further request you to adjust my ledger balance as early as possible by taking for the refunded amount of rs 364.
Thanking you advance.
Yours faithfully
Kajal ghosh
