State Bank Of India [SBI] — Cash withdrawal issue

Address:

SBI Kanithi road branch

I got only Rs. 300 when I withdrawn Rs. 1500 from ICICI bank ATM (Tech Mahindra, Vizag) with SBI ATM card. So I raised a complaint against it with Customer support and they said that they will resolve the issue within 7 working days. But it's been 13 days since the issue happened. So I called them again and they said they'll resolve it as soon as possible but instead they closed the ticket without resolution very soon after I contacted them. End of the day I lost Rs. 1200. Please take a necessary action on this
