State Bank Of India [SBI] — CDM hardware error

Address:	Mumbai City, Maharashtra, 400020
Website:	Www.sbi.co.in

I used a cash deposit machine at Churchgate, Mumbai(1821) on the 8th of November at 15:45 to deposit Rs.7200 but a I did so the machine showed a hardware failure and took the money in which did not reflect in my account balance.
I immediately filled a form regarding the issue with the concerned branch and I was assured that within 2 days my money will be credited but it's already been 5 days and nothing has been done.
The customer service call centre is also of no use as they're rude and do not seem to want to help people
please look into the matter as this amount is a lot for a student like me.
The CCTV footage will supplement my claim and will show that I have deposited the cash.
