State Bank Of India [SBI] — extra money drawn apart from the respective withdrawal amount

Address: Nagaon, Assam

On 8 the of september 2017 an amount of ten thousand rupees only was withdrawn from a/c xxxx 4305 on 080927 at atm s1bw[protected] txn#5426. But within one minute another message was received in my phone number [protected] that an amount of another twenty thousand has been withdrawn from the same account as above. I withdrew only ten thousand rupees and owns no idea of the 'twenty thousand ' amount. I kindly request the concerned authorities to look into the matter.
