State Bank Of India [SBI] — banking transaction

Address:

Darrang, Assam, 784125

I wanted to deposit 4000 rupees by cdm1 in mangaldai branch which is my savings account. But when i started to cash deposit by cdm, the machine showed me in display, hardware error, there after again showed me ' the last transaction cancelled'. Then i checked my account mini statement but the amount did not deposit my account. There after i submitted a application mention that all along with a receipt which i received by cdm machine when i wanted to cash deposit.
This transaction was 31-03-18, till now the bank does not response me. So i request to take action against the bank...
