On 26th december 2017 in sbi in touch quest mall at 11.50 am we have tried to deposit rs.32000 into the machine. The machine accepted and credited rs. 17500 and returned only rs.10, 500 to us. Rs.4000 was taken without being credited to the account.
Immediately we went and spoke with the branch manager who apologized and said that this has been happening with numerous people that day. She assured us the amount will be credited to out account the very next day. However nothing of that sort happened and we had gone several times only to be assured that it will be returned the next day. It's been 10 days since the incident and we haven't received our money back.
A written complaint has also been submitted to the bank with no response yet
